Controls
The controls are quite easy and simple. A button to jump and
hold down the down button and press the A button to spin. Here's the specific
moves for each characters.
Sonic
Jump - A button
Slash Jump - Press the A button twice.
Spin Dash - Hold the down button, then, press A to spin. Release both buttons to
spin towards a direction or enemy.
Fire Dash - You must get the Fire Shield first. Then, press A button twice to do
it.
Double Electric Jump - You must get the Electric Shield first. Then, press A

Breaking Walls - This is an automatic move. Knuckles will automatically destroy
walls that he can destroy with his knuckles.
Super Sonic
Super Sonic is twice faster than the normal Sonic and can jump higher and
totally invisble. Of course, getting crushed or landing into endless pits will
cause Super Sonic to die.
To maintain this form, you must have rings once you become Super Sonic since
rings will be drained out. Also, you must get 7 Chaos Emeralds to become Super
Sonic.
Once you get 50 rings, double jump to transform into the gold Super Sonic! Of
course, his looks will be different and do different actions.
Jump - A button
Spin Dash - Hold the down button, then, press A to spin. Release both buttons to
spin towards a direction or enemy.
Super Knuckles
Super Knuckles can be obtained by using Knuckles. You must get the seven Chaos
Emeralds in order to transform into Super Knuckles. Double jump with 50 rings to
change. This is similar like Super Sonic where Super Knuckles is much
faster.
Jump - A button
Climb - Jump towards a wall (certain walls can't be climbed) and Knuckles will
automatically hang onto the wall. While on the wall, move the direction keys to
move on the wall. To jump off the wall, press the A button.
Glide - Press the A button twice and Super Knuckles will glide lower.
Breaking Walls - This is an automatic move. Super Knuckles will automatically
destroy walls that he can destroy with his knuckles.
Mushroom Hill Act I
Head right and go past the Butterdroids. Run through
the loop de loop and roll down the hill. Collect the Super Shoes for a
speed boost. Ignore the pulley lift nearby and proceed right. Climb
up the poles and run through the loop de loop. Use the pulley lift above
you to go up. Press Up and Down to make the pulley lift go up and down,
respectively.
Use the two mushrooms to raise Sonic higher, so you can access the spring above
you. Bounce on it and speed through the loop de loop. Use this swing
lift to send Sonic over to the right. Head across the vine-shaped bridge
and drop the pole at the bottom right. You'll land next to a secret
passageway containing
a Giant Ring.
Exit the passageway by going right, and use the swing lift to hoist Sonic up to
a vine-shaped bridge. Drop down and go past the Starpost. Run down
the hill and drop down again to find a pulley lift. To the right of it is
a hidden passageway containing a Giant Ring.
Exit the passageway and use the pulley lift. Run through two loop de
loops. When you nearly reach a mushroom at the top, stop running left and drop
down to the right. Continue onward to find a passageway containing a Giant
Ring. When you exit the passageway, watch out for the Dragonfly on patrol.
Run down the loop de loop and climb up the poles to find a Starpost. Go
past it and head right to meet the Mini-Boss.
Mushroom Hill Mini Boss - The Log Cutter
The machine will throw logs at you in a vertical direction.
If you have the Fire Shield, hit it from below to destroy. Alternatively, wait
for it to come down before jumping on top of it to attack it. 6 hits and the
mini boss will explode.
Mushroom Hill Act II
Go right and run down the hill to meet Knuckles. He
pulls a lever, sending you hovering upwards. When you land, you'll notice
that the seasons have changed and that it's Autumn now. Collect the
Invincibility and go right. Use the mushroom seesaws and run through the
loop de loops. Drop through the gap nearby and use the pole to hoist Sonic
upwards. Use the spring to go up the
loop de loop and find a passageway containing a Giant Ring.
Drop down and use the pulley lift nearby. Go right and use the mushrooms
to send Sonic up to a Super Ring and an Invincibility. Use the spring to
go over to the right. Go up the loop de loop and use another spring.
When you land near a spring and a mushroom, drop down to the left and head right
to find a hidden passageway containing a Giant Ring. Now exit the
passageway and use the seesaw to land on a spring above.
Head across the vine-shaped bridge and go past the Starpost. Use the
pulley lift and bounce on the red spring to catapult Sonic over to the swing
lift. If you can use the springs to bounce Sonic over to the right, you'll
land near a loop de loop. When you come across a Cluckoid, go past it to
find a hidden passageway containing a Giant Ring.
Run through the loop de loops and use the pulley lift to go upwards.
Before you do so, go past the Cluckoid and enter the hidden passageway to find a
Giant Ring. When you make it to the surface, go right and use the mushroom
seesaws. Go past the Starpost to see a satellite dish emitting signals.
Mushroom Hill Boss - The Speed Boost O'Matic
Jump on the satellite dish to destroy it, revealing Robotnik's machine in the process. If you can hit him a few times, the Boss Battle will be easier to win. When Robotnik flies off to the right, chase after him and follow him through an obstacle course. When you are running through the obstacle course, jump to avoid the spikes. If you keep running, you'll catch up with Robotnik. When he switches off the boosters, you can hit him. If you have a Flame Shield, the boosters won't hurt you, so you can attack Robotnik repeatedly.
8 hits and Robotnik's machine starts to explode, but Robotnik still isn't worried. However, his machine soon crashes into a tree and it falls apart. When you've opened the Prison Egg, Sonic will look up and you'll see the Flying Battery Blimp fly past. Robotnik flies up in his Egg Pod and enters the battleship. Sonic immediately jumps up and grabs onto it. Onward to the next level...
Flying Battery Zone Act I
Flying Battery Zone is a remade version of Sonic 2's Wing Fortress Zone. It's quite the change from the nature of Mushroom Hill Zone. Obstacles include flame blasters, Prison Eggs, mines, and crushing platforms. In Act 1, you'll be underneath the battleship for a while, so be ready. I think Act 2 is easier. If you follow this Walkthrough, you should be prepared for the many obstacles in this level.
Go right and head through the purple cylinder. Go down
the platform and head left. Go past the flame blasters and head right.
Outside the Flying Battery, hop across the platforms and use the levers.
Jump onto the ledge and go up to re-enter the Blimp.
Go past the Starpost and make your way through the purple cylinders. Spin
Dash up the slope and position Sonic on the flame blaster. After being
catapulted upwards, go right and use the moving platforms to go over to the
flame blaster. If you open the Prison Egg, Badniks will emerge from it, so watch
out.
Use the flame blaster to go upwards. Go past the mines and use the poles.
Drop down and go left. Jump over the speed boost and go past more mines.
Go down the platform and head right. Wait for the platforms to rise to
avoid getting crushed.
Go past the Starpost and press the switch. Drop down and go left.
Spin Dash up the slopes and jump on the Prison Egg. Run through the purple
cylinders and drop down. Go right and head past the Starpost. Go up
the slopes and use the moving platforms.
Jump on the Prison Egg and use the spring. Go right and wait for the
missiles to uncover an opening for you to drop through. When you drop
down, run through the purple cylinder and head past the Starpost.
Flying Battery Zone Mini Boss - The Bad Tempered Animal Trap
When you come across the machine, it will be disguised as a Prison Egg. Jump on the plunger to reveal two spiked arms. To destroy this Mini-Boss, you make it attack itself. Position Sonic on the plunger and wait for one of the spiked arms to proceed to hit you. When it does so, run off the plunger. The machine will be hit instead.
Flying Battery Zone Act II
Go right and head up the purple cylinder. Jump on the
springs and go past the mines. Drop down and head through the purple
cylinder. Press the switch and go down. Head right and press another
switch. Go down the whole way and head left.
Go past the Starpost and press the switch. Go up and use the spider to go
across the purple cylinder. Run past the mines and press the switch.
Drop down and go through the purple cylinder. Go past the Starpost and
press the switch.
Go right and jump on the flame blaster to undo the cork screw. Drop down
and go past the Starpost. Press the switch and Spin Dash to avoid getting
crushed. Press two more switches and drop down. Go right and use the
platforms.
Go past the mines and use the spider. Go down and press the switch.
Go past the Starpost and head left. Go up and head through the purple
cylinder. Use the moving platforms to get to the top and meet another
Mini-Boss. Yes, there are two Mini-Bosses in the Flying Battery.
Flying Battery Zone Mini Boss - The Laser Machine
Robotnik unleashes a laser machine on you. It is similar to Sonic 2's Wing Fortress Zone Boss. This time, however, you can't destroy it. You must make it destroy itself. Each time it fires a laser, it will damage itself and cause the room to cave in. If you have a Lightning/Water Shield, you can hit the machine, but it won't have any effect. Eventually, the machine will explode and Robotnik will run off.
Follow the path, and a platform will start ascending. Keep running until you arrive at the final spikes. The platform will take you up and it'll eventually stop rising. When it does so, Robotnik will swoop down and appear in the centre of the screen.
Flying Battery Zone Boss - The Swing O'Matic
When Robotnik appears, he'll swing up and down. When he's doing this, you can attack him. After swinging for a moment, Robotnik will move his machine towards you. If you position Sonic underneath it, Robotnik will fire a flamethrower at you. When, Robotnik approaches you, jump over to the opposite side of the screen. When Robotnik starts swinging again, you can hit him. 8 hits and he will explode.
When the Prison Egg is opened, you'll automatically run right and go through a hallway. Sonic jumps off the battleship and lands in Sandopolis Zone.
Sandopolis Zone Act I
When you land in the sand, jump up. Go right and push
the yellow block. Ride it and go down the slides. Run down the slope
and grab the pulley lift. Go right and run through the loop de loop.
Push the yellow block and ride it. Use the swings and go left.
Collect the Invincibility and go up. Go past the Starpost and head down
the slides. When you land in the quicksand, jump over to the right.
Push the yellow block and ride it. Spin Dash up the slope, and use the
platforms to go up the slide. Run through the loop de loop and use the
pulley lift.
Push the yellow block and ride it. Go right and then up. Use the
swing and go past the Starpost. Use the pulley lift and push the yellow
block. Ride it. When you drop down, go right and head down the slopes.
Use the swings and go left. Run through the loop de loop and go up.
Go right and use the pulley lift. Go past the Starpost and head right.
You'll see a pyramid rise from underneath the sand. When the entrance
opens, the fight with the Pyramid Guardian begins.
Sandopolis Mini Boss - The Pyramid Guardian
When the Pyramid Guardian approaches you, jump over him, so he turns away from the quicksand. Now you can attack! Hit the Pyramid Guardian on the head, before he has the chance to jump. He will then fall to a pile on the floor and move back 2 spaces. When he stands back up, hit him again and send him back 2 spaces. Do this 3 - 4 more times and he will fall into the quicksand. However, be careful not to fall in yourself or you'll die!
Now you will enter the Pyramid and the story continues...
Sandopolis Act II
Go right and pull the levers to turn on the lanturns.
Head right and push the black block to the right. Go through the opening
and go up. Go left and collect the Invincibility. Push the black
block to the left and leave. Run through the loop de loop, and you'll
release the ghosts from the Prison Egg.
Push the black block to the left and go through the opening. Press the
lever and go down the slides. When you see a swing above a particular
slide, jump onto it and go past the Starpost. (If you don't jump onto the
correct slide, you'll go down an infinite loop of slides instead. To continue
through the level, wait for Sonic to land near the correct slide again and try
to jump onto it this time.) Push the black block to the left and go up. Push the
yellow block and ride it.
When you get through the opening, jump on the swing and use the pulley lift.
Push the black block to the right and go up the opening. Go right and run
through the loop-de-loops. Go past the Starpost and push the black block
to the right. Jump on the swing and press the lever.
Go through the opening and break the container. When the sand rises, go
left and then up. Jump on the swing and push the black block to the left.
Go right and head through the opening. Break the container and press the
lever. Go right and then left. Push the black block to the right to
reveal an opening.
Go through the opening and push the black boulder to the right. Go right
and jump on the swing. Press the lever and push the black block.
Jump down the opening and go right. Jump on the swing and use the pulley
lift. Go right and press the lever.
Run through the loop de loop and go left. Use the pulley lift and head
right. Go past the Starpost and head down the slide. Run through the loop
de loop and use the spring to land on the slide. Go down the slide and run
through another loop de loop. Go right and use the lever.
Use the moving platforms and go right. Push the black block to the right,
and press the lever. Use the swing and break the container. Go
through the opening and press the lever. Go past the Starpost and push the
black block to the right. Jump down and go right to meet the Boss.
Sandopolis Boss - The Egyptian Themed Robot O'Matic
When the Egyptian-Themed Robot moves towards you, Robotnik will charge up his laser cannon and fire a small laser at you. If you stay away from the robot, you should be able to dodge it. Robotnik will use his 2 hands to crush you, but you can use them to climb up the robot and hit the laser cannon. The armour of the robot will fall apart, revealing Robotnik in the process. Hit him a few times and jump off the robot, as the armour will cover it up again. Repeat 6 times and the robot will be toast!
Once you have opened the Prison Egg, you'll automatically head right and Sonic will fall into the depths of Lava Reef Zone.
Lava Reef Zone Act I
When you land, drop down the two ledges and Spin Dash through
the boulders. Press the switch and go through the opening. Hop across the
rocks. If you fall into the pool of lava, you'll get hurt. Go right
and climb up the steps. Avoid the flamethrowers as you do so.
Collect the Invincibility and go right. Run down the slope and go across
the pool of lava. Press the switch and go through the opening. Spin
Dash through the boulders and run through the brown cylinder. Run left and
go past the pool of lava. The Death Egg can be seen in the background.
It seems Robotnik is repairing the space station in this level (a la Launch Base
Zone).
When you reach the waterfall of lava, wait for an opening to appear before
crossing it. Use the spring and jump over to the Starpost. Collect
the Flame Shield and go left. Destroy the switch and go through an
opening. Jump on the black platform and position Sonic to the left.
Spin Dash to lower the platform.
Go right and press the switch. Go through the opening and make your way
down the steps. Head across the waterfall of lava and press the switch.
Go through the opening and head right. You can attack the drilling machine
if you want to, but it'll fall into the pool of lava, destroying it.
When you land, hop across the rocks and press the switch. Climb up the
steps and Spin Dash up. Spin Dash through the boulders and use the moving
spiked platform. Go left and use another platform. Climb up the
steps and press the switch. Go through the opening and use the platform.
When the moving platform rises, jump down and head right. Spin Dash
through the boulders and go past the Starpost. Run down the slope and
collect the Flame Shield. When the ledge collapses, go down the steps and
head right. Go across the bridge and run down the black tunnel.
Go left and destroy the switch. Run through the opening and head down the
slope. Watch out for the spiked ball as you drop down the gap. Go
right and climb up the steps. Head across the waterfalls of lava.
Press the switch and go through the opening. When the lava rises, wait for
it to sink before crossing the platforms.
Go past the Starpost and Spin Dash through the boulders. Use the moving
platforms and press the switch. Go through the opening and climb up the
steps. Press the switch and run through another opening. Spin Dash through
the boulders and go down the slope. Press the switch and go through the
last opening. Head past the Starpost.
Lava Reef Mini Boss - The Hand Machine
Although the Mini-Boss is the Hand Machine, there are also two wheels for you to contend with. They will fire small projectiles at you, so run back and forth to dodge them. Each wheel takes 4 hits to destroy. If you concentrate on destroying one wheel, you can deal with the other one during the next attack sequence. You don't need to take the wheels out, but their attacks can be a nuisance, so I advice doing so. When the wheels leave the screen, the Mini-Boss will make an appearance. The hand will copy your movements in an attempt to pound the ground and crush you. If you keep running back and forth, you should be able to dodge it. When it pounds the ground, hit it once.
Lava Reef Act II
When the pool of lava freezes over, go right and head across
it. Press the switch and go through the opening. Head across the
blue cylinder while avoiding the row of spikes. Dodge the Robotnik Boxes
and use the moving platforms to go to the top. Head right and run down the
slope. Drop down and go left.
Drop down the ledge and go down the steps. Spin Dash through the walls and
use the spring. Jump onto the moving platform and go left to find a hidden
passageway containing a Giant Ring. Drop down and go left. Head past
the moving spikes and run down the slope.
Go right and jump over the flamethrowers. Press the switch and enter the
opening. Use the spiked platforms and go right. Head past the
Starpost and use the spring. Jump across the platforms while dodging the
spikes. Go left and press the switch. Enter the opening and head
past the flamethrowers.
Use the spiked platforms and go right. Press the switch and enter the
opening. Use the blue cylinders as pulley lifts. Go left and use the
spring. Collect the Flame Shield in the hidden passageway and jump across
the two platforms. Enter another hidden passageway to find a Giant Ring.
Leave the passageway and go right.
Go past the moving platforms and Spin Dash through the walls. Go down the
black tunnel and Spin Dash over the flamethrower. Head past the spikes and
drop down the collapsing ledges. Go left and press the switch. Run
down the slope and head past the Starpost. Press the switch and enter the
opening.
Hop across the ledges and go up the platforms. Head past the flamethrowers
and use the spring. When you land on a platform, go right and climb up the
steps. As you do so, you'll see the Death Egg in the background once again.
It seems the repairs are complete, and Robotnik plans to use the Master Emerald
as a power source to launch the space station. When you reach the end of
the steps, you'll meet Knuckles. He pushes a boulder down the steps,
causing you to fall into the abyss below...
Lava Reef Act III
When you land, you'll see the Death Egg in plain view.
After Robotnik demonstrates its blasts and heats up the lava, he'll appear in
the background. Robotnik fires eight missiles at you. Hop across the
platforms to dodge them. When the screen continuously scrolls to the right, jump
across the collapsing ledges one by one. This is a difficult area to get
through, as you can lose a life, by moving too slowly or falling off the
platforms/ledges.
When you reach the Starpost, go past it and hop across the platforms. When
the screen stops scrolling to the right, go back the first platform to find a
Flame Shield nearby. Collect the Flame Shield. It'll make the Boss
Battle coming up much easier. Position Sonic on a platform and wait for it
to descend. When you reach the waterfall of lava at the bottom, Robotnik
will emerge from the
lava on the right side of the screen.
Lava Reef Boss - The Lava Mine O'Matic
When Robotnik appears, he'll tilt the lava in his direction. If you've collected the Flame Shield, you can go left and hop across the platforms to avoid sliding into Robotnik. When Robotnik launches 3 mines, jump on the platforms to dodge them. If you get hit, you'll lose the Flame Shield, making this Boss Battle harder to win. The 3 mines will hit Robotnik one after another. When Robotnik sinks into the lava, he'll emerge in the opposite direction and repeat his attack pattern.
When a Prison Egg starts to descend from above, be aware of the lava that is still around you. If you fall into it by mistake, you'll lose your Rings or lose a life, so wait for the Prison Egg to reach your jumping distance first. Once it's at a reasonable height, jump up to hit its plunger. After the lava freezes over once again, you can safely go across it and enter Hidden Palace Zone.
Hidden Palace Zone Act I
"Some mysteries are solved! Robotnik makes his big play, and
Knuckles finds out
who the REAL bad guy is!"
The above statement is the Instruction Manual's description of this Zone, and
that's generally what happens in the Hidden Palace. It is the shortest
Zone in the game, due to the fact that its purpose is to show Robotnik's true
colours to Knuckles. On a side note, when you go to the Level Select menu,
you don't actually see the Zone's name on the screen. It's referred to as
Act 4 of the Lava Reef Zone instead.
Anyway, back to the Walkthrough. Go right and head up the steps. If
you're playing as Tails, you can fly up to find every type of Item Box at the
top left and right. Use the teleporter and go past the Starpost.
Head right to meet Knuckles. The echidna finally challenges you to a
battle. The ancient stone tablet displayed above shows a picture of Sonic
unleashing incredible Emerald forces in a showdown with Robotnik. This
event takes place in The Doomsday Zone.
Hidden Palace Mini Boss - Knuckles the Echidna
In comparison to your recent Boss Battles, Knuckles is easy to defeat. If you Spin Dash towards him, he'll block it, so don't bother. If Knuckles Spin Dashes, jump over him. Don't Spin Dash to counter Knuckles' Spin Dash, since you'll still get hurt. When he glides, hit him from behind. If you Spin Dash towards Knuckles the moment he lands, you can hit him, but it's tricky to do. 4 - 5 hits and he will be out for the count!
After the battle, a series of explosions occur. When
Knuckles runs off to investigate, chase after the echidna and you'll see
Robotnik stealing the Master Emerald from the Emerald Chamber. (If you're
playing Sonic 3 & Knuckles, you may notice grey/coloured Super Emeralds here,
depending on whether you have collected the Chaos/Super Emeralds in Special
Stages.) Knuckles realises that Robotnik is the true villain, but it's too late
- the mad doctor has stolen the Master Emerald!
As Robotnik flies off, you automatically head right. Knuckles attempts to
stop Robotnik, but he electrocutes the echidna and makes his escape.
Robotnik can take infinite hits, so don't bother attacking him. When the
floor around you collapses, you'll land in another area. Knuckles awakens
and breaks down a wall. He runs left and shows you a teleporter.
Sonic jumps onto it and istransported to Sky Sanctuary Zone.
Sky Sanctuary Zone Act I
Like Hidden Palace, Sky Sanctuary is no ordinary Zone.
There is only one Act in this Zone, and it is divided into three Boss Battles.
They're a blast from the past for players of Sonic 1 and Sonic 2.
When you arrive, you'll see the Death Egg rise from underneath the clouds. It is
powered by the Master Emerald and piloted by Robotnik. He dispatches an
armada of EggRobos to patrol the Sky Sanctuary Zone, so be ready for them.
Knuckles presses a switch to create a bridge for you to cross.
Jump on the vines and go right. Run down the slope and head up the green
tower. Jump across the black pillars and go left. After the
fountain, go past the EggRobo and hop across the black pillars. Jump over
the clouds. You'll fight Metalex the Metal Sonic from Sonic CD. It
seems Robotnik dispatched him to stop you from reaching the Death Egg. The
robot will battle you on three separate occasions throughout this level.
The first two Bosses are carbon copies of Sonic 1's Green Hill Zone Boss and
Sonic 2's Metropolis Zone Boss.
Sky Sanctuary Zone Boss: Metalex's Chained Ball O'Matic
When Metalex the Metal Sonic appears on the right side of the screen, jump on one of the two platforms and hit him twice. As Metalex reveals his chained ball, stay underneath the right platform to avoid getting hurt. When he swings the ball to the left, jump on the platform and hit him. You should bounce off him and land on the platform without getting hurt. Repeat this strategy 6 times to win.
Sky Sanctuary Zone Act II
Use the teleporter and go right. Head past the Starpost and grab the vines. Hop across the black pillars and use the vines. Collect the Flame Shield and go right. Jump across the clouds and go past the spiked swing. It's time for another show down with Metalex the Metal Sonic.
Sky Sanctuary Zone Boss: Metalex's Sphere Cloning O'Matic
When Metalex appears in the centre of the screen, use Sonic's Insta-Shield to hit him. Although eight spheres are protecting Metalex, you'll still get score hits against him and you won't get hurt. If you're Tails, you can fly up and hit him. As long as Metalex remains in the air, you won't get hurt if you attack him. This is due to a glitch, which wasn't in the original Metropolis Zone Boss. When you hit Metalex, he'll release one of the eight spheres and stay in the air. If you destroy the spheres, Metalex will descend, so I advice ignoring them and concentrating on hitting him. 8 hits and he will explode...
Sky Sanctuary Zone Act III
Use the teleporter and go left. Head past the Starpost and use the spiked swing. Go up and jump across the clouds. Go right and head past the spiked swings. Use the teleporter and apprach the tower. When you see the birds, wait for a moment and take out the EggRobo that appears. Go up the bridges and head past the Starpost. Use the teleporter to transport Sonic to an boss area where you have a final showdown with Metalex.
Sky Sanctuary Zone Boss: Metalex
Metalex's attack pattern is similar to that of the version of Metalex from Sonic 2's Death Egg Zone. Fortunately, this battle is much easier, since you have Rings and Metalex's pattern isn't difficult to predict. He will spin around the screen and he will do two attacks. If he charges towards you, jump to dodge the attack. If he spins towards you, learn his pattern, so you can avoid the attack. You can only hit him when he isn't spinning. Once you get the hang of countering Metalex's attacks, this battle should be over soon enough.
As Metalex short-circuits, the boss area apart and Sonic jumps onto a tower. He runs up the collapsing spiral pathway and jumps onto the rising Death Egg... However, if you are playing as Knuckles, you will fight a slightly different boss and this is where the game ends for you...
Death Egg Act I
Death Egg Zone is the final level of Sonic & Knuckles if you haven't collected all 7 Chaos Emeralds. Obstacles include electric bridges, electric walls, collapsing platforms, conveyor belts, sound wave machines, anti-gravity passageways, and reversed gravity. While this Zone isn't easy, it isn't too hard either, in comparision to Sonic 1's Scrap Brain Zone and Sonic 2's Metropolis Zone. If you follow my Walkthrough, you should be able to complete this level without too much problems.
Take out the Spikebonker and go across the electric bridge.
Use the collapsing platforms and head right. When the electric wall is
active, use the speed boost and grab the pulley lift. Go left and collect
the Water Shield. Use the moving platform and head through the
anti-gravity passageway.
Use the moving platform and go right. Head up the steps and go across the
conveyor belt. When you arrive at the Starpost, jump up the electric
bridges and climb up the steps. Grab the pulley lift and head right.
Use the sound wave machine and go down the steps. Run through the
anti-gravity passageway.
Go down the conveyor belt and head across the electric bridge. Go left and
cross another conveyor belt. Watch out for the rockets that are launched
at you, when you ride the next one. When you reach the Starpost, jump over
to the right immediately to avoid falling into the gap and losing a life.
Climb up the steps and go through the anti-gravity passageway. Press all
six switches on the moving platform and go through another passageway.
Use the speed boost and go left. Use the sound wave machines and climb up
the steps. Go past the Starpost and head right to meet the Mini-Boss.
Death Egg Mini Boss: The Evil Eye
In my opinion, this is the hardest Mini-Boss in the game.
When the eight balls circle around the machine on the floor, you can hit the
eye. Unfortunately, each time you do so, one of the balls will explode,
scattering tiny spikes everywhere. It can be difficult to avoid them.
If you lose your Rings, try to get them back quickly, so you can hit the eye
constantly. When the balls extend themselves, wait for them to circle
around the machine again, so you can hit the eye.
When all the balls are destroyed and you've hit the eye 8 times, there will be
an explosion and the eye itself will attack. It looks like this Mini-Boss
Battle is far from over. There are now 2 spiked platforms circling around
the eye. You must jump on these platforms to hit the eye. stay on
the platform as the laser fires and you will not be hurt. Repeat this 6 times to
defeat the eye.
Death Egg Act II
After the armour of the Death Egg is destroyed, you'll be
sent hovering upwards. You'll notice that the background has changed.
It seems the space station has been orbiting around Sonic's home planet Mobius
for some time now. Anyway, go right and head across the electric bridge.
Go through the anti-gravity passageway. From this point, there will be
reversed gravity at different times throughout the level.
Head across the electric bridge and go through the anti-gravity passageway. When
you have to choose which direction to go in next, take the eastern route, as
it's the easiest path to get through. Climb up the steps and go right.
Head across the conveyor belt and climb more steps. Go left and use the
elevator.
Go right and head across the electric bridge. Hop across the moving
platforms and go down the conveyor belt. Head past the Starpost and go
down another conveyor belt. This one is much harder to get through, as it
is on the ceiling. Try to dodge the rockets by jumping constantly.
Go left and use the springs. Go right and use the elevator. When you
reach the dropping platforms, stand on the last one to the left and wait for the
last one to the right to rise. When it does so, hop onto it and jump over
to the right. Watch out for the electric ceiling as you go past the
Starpost.
Head across the conveyor belt and use the elevator. Go left and use the
sound wave machine. Go right and use another machine. Go through the
anti-gravity passageway and use the machine. Climb up the steps and take
the elevator. Board the next one and go down the steps. Ride the conveyor
belt and go past the Starpost. Take the elevator to face another
Mini-Boss. Like the Flying Battery Zone, there are two Mini-Bosses in this
level.
Death Egg Mini Boss: The Pinball O'Matic
When you appear on the right side of the screen, you'll see Robotnik behind a wall, controlling his machine. You can't destroy this Mini-Boss by yourself. You must use the 4 elevators to change the gravity and cause the spiked robots to hit the machine. If you are on the ceiling, you can Spin Dash to change the position of the spiked robots, so the spikes can hit the machine. This can be tricky to do, though. When a spiked robot damages the machine, tiny spikes will be sent around the screen. If you enter the elevators, you can avoid getting hurt by them. Repeat this 8 times and the machine will explode.
When the machine explodes, the wall behind Robotnik crumbles and Sonic chases after him. Like the finale of Sonic The Hedgehog 3, you'll now have to fight 3 Bosses one after another. If you lose a life from this point, you'll start the Boss Battles without any Rings, so try to make your first play through count. When Robotnik locks himself inside a giant robot, the floor to the left will start to collapse, so run right to avoid falling off the screen.
Death Egg Boss: The Egg Emperor
When the floor starts shaking, you'll see Robotnik's Giant Robot appear on the left side of the screen. He uses the robot's six fingers to pound the floor. You must hit the fingers 18 times, as each finger takes 3 hits to destroy. You can Spin Dash between the two sets of fingers to take them out more quickly.
When all the fingers are destroyed, Robotnik's Giant Robot will sink into the floor. As the floor starts to collapse again, you'll see the Giant Robot surface on the left side of the screen.
Death Egg Boss: The Laser O'Matic
When the Giant Robot appears, the floor will start collapsing continuously from this point. As Robotnik fires a flamethrower at you, jump to dodge it. Hit the robot to reveal its power source - the Master Emerald! When Robotnik begins charging up the laser cannon, hit the Emerald once and wait for the cannon to charge up. When it does, jump up IMMEDIATELY to dodge the huge laser. If you're playing as Sonic & Tails, Tails will copy your moves, so you can probably hit the Master Emerald more than once during each attack sequence. Him him 8 times and he will fall into outer space!
Of course, Robotnik isn't going to go down that easily. As the exploding Giant Robot leaves the screen, he grabs the Master Emerald and tries to escape.
Death Egg Boss: The Final Chase
For those of you that have not collected all the Chaos Emeralds, this is the final showdown with Robotnik. As he flies off, the floor will start collapsing continuously again. You must run right and chase after Robotnik. Hold Right to keep running fast. If you're move too slowly, you'll fall off the screen. You'll probably only be able to hit Robotnik once each time you get near him, so be patient. If you're playing as Sonic & Tails, you may be able to hit Robotnik more than once. 5 hits and the Emerald will drop to a platform and you will see a final explosion. For those of you that have all the Chaos Emeralds, the battle is far from over yet!
Doomsday Zone Act I
When the Death Egg exploded, Robotnik stole the Master Emerald while Sonic was distracted. You can only access this zone if you have collected all seven Chaos Emeralds. As Super Sonic, you must fly through the asteroid field to retrieve the Master Emerald from Robotnik. Note that you lose Rings for every second that your character is in his Super Form, so you must collect Rings to increase your Rings gauge. Otherwise, you'll turn back into your regular character. Consequently, you'll lose a life and have to repeat the level.
Upon transforming into Super Sonic in outer space, make your way through the
level while avoiding the asteroids and missiles. I haven't written a
walkthrough for this level, as it is difficult to write one, since it would be
hard to understand, in my opinion. Instead, I've written some general
hints and tips.
Try to fly up and down to collect the Rings that you see as you progress through
the level. If you remember the layout of this level, it's possible to
collect a lot of Rings. I've often managed to get 100 Rings here. If
you follow the paths of rows of Rings, you'll be able to dodge most of the
asteroids and missiles. Both asteroids and missiles can slow down your
movement, but this only lasts for a few seconds, as you can break through the
latter and destroy the former. Eventually, you'll leave the asteroid field
and catch up with Robotnik's spaceship.
Doomsday Boss: Robotnik's Spaceship
If you've got nearly 100 Rings, you'll have plenty of time to win this Boss Battle. If you've got around 70 Rings, it's best to win as soon as possible. Robotnik fires tiny projectiles and launches three missiles at you. You must trick the missiles into hitting the upper right grey part of the spaceship. Lead the missiles into the grey part, damaging the spaceship in the process. The projectiles and missiles can stop you for a moment, but the latter will be destroyed if they hit you. Use the A, B or C Buttons to speed up, so you can lead the missiles towards the spaceship quicker.
As the spaceship explodes and falls down to Mobius, Robotnik will appear in a giant robot (not again?) and try to escape with the Master Emerald. You must enter another asteroid field to stop the extremely evil and mad doctor once and for all!
Final Boss: Dr. Robotnik's Giant Robot
This Boss will look familiar to Sonic 2 players because it is
the same design as the Final Boss from Sonic 2's Death Egg Zone. This
time, however, Robotnik will only shoot missiles and spikes at you, and he will
be constantly trying to run away from you. If you fly at your normal
speed, you won't get to Robotnik in time to defeat him, so press the A, B or C
Buttons repeatedly to catch up
with him. Since you can collect Rings, this final fight is actually easier
than the previous battle. Simply charge into Robotnik to hit him. If
he launches missiles or spikes at you, ignore them. Since you're Super
Sonic, they can't hurt you. They may pull you back a little, but if you
concentrate on attacking Robotnik, this battle should be over soon enough.
As the Giant Robot explodes and falls apart, Super Sonic will grab the Master Emerald. Congratulations! You have completed Sonic & Knuckles! Now enjoy the ending.
Ending
If you collected all 7 Chaos Emeralds, Super Sonic will bring
the Master Emerald down with him from outer space. When Super Sonic enters
Mobius' atmosphere, Tails appears in the Tornado and grabs the Master Emerald.
You turn back into regular Sonic and land on the biplane. Sonic and Tails
return to the Floating Island and leave the Master Emerald in Angel Island Zone.
As Floating Island rises into the sky, Sonic and Tails leave in their plane.
If you obtained 0-6 Chaos Emeralds, Sonic will fall from outer space, but the
Master Emerald will remain there. When Sonic enters Mobius' atmosphere,
Tails appears in the Tornado. You'll land on the biplane and return to the
Floating Island. The island remains in the sea as Sonic and Tails leave in
their plane.
When you complete the game, watch the credits roll and you'll eventually see a
short scene at the end, depending on whether you collected all 7 Chaos Emeralds.
If you did, you'll see the wreckage of the Death Egg and one of Robotnik's
EggRobo Badniks emerging from it. This is the same EggRobo that drops a
bomb in Knuckles' intro scene and pilots the vehicles in his adventure.
If you didn't, you'll see Robotnik with the Master Emerald.
