Complete Walkthrough of Level 3 (Mega Phoenix)

==You can start from this level without missing stuff from previous level(s).==

First look behind you. You should see a locked door. Remember this door. Then, first turn left and destroy a Class 1 Platform Robot to get a Super Laser boost. Next destroy the Medium Hulk behind. The rest is straight forward - just go down the path, destroying the robots you meet, grabbing the stuff you see (the first 3 robot makers have power-ups each, except for the last which holds Smelter II.), until you reach the Red door. (The red key is dropped by a red Omega which drops Smart Mines.) Now is the GREAT problem.

Go through the red door, and look up. You should see a Cloaking Device above you. Do not venture along the corridor yet - you will find that a wall closes on behind you. Now, look far out. Do you see a grating at the end of the corridor? This is it. Stay where you are (below the cloak). Shoot towards it and you should hit a switch, opening the cloak above you.

If you shoot slightly up again, you may be able to hit the ceiling beyond the grate, being notified that a door is locked. Now take the cloak and fly to the grate and you should see some power cell textures and the yellow door sign on the walls around the grate. Remember these textures.

Next, go out to the boss room. You should see a wall behind you as you go out. This wall can be opened once the boss is destroyed. Look to the right of the lava, and you should see a small patch of moving lava. Inside is an Invulnerability actually. At the lava below there is a Guided Missile behind a lava fall. If you take it, you will see that there is a wall with a lava tunnel inside.

Head for the Energy Center first. You should find that there is an Earthshaker above you, unreachable because of a grate. Notice the 2 yellow door signs on the walls. Look down, and you will see a lava tunnel with a Mega Missile, 2 Energy boosts and a Guided Missile. Go down to the end of the tunnel, and you should see another grate and a switch behind plus a shield boost. Notice the yellow door textures on the wall. These signs point that the 3 places are related in a manner. Shoot the switch, and the door inside the grate at the ceiling is opened (it stays opened).

SAVE GAME. Having your cloak still on (hopefully), fire a Guided Missile through the grate and fly up and you will pass the area where you took a Guided Missile below the boss room. Fly the Guided Missile to the switch where you opened the wall to a cloak, swerve right up and finally you should find a hidden switch. Hit it, and this switch will open the wall trapping the Earthshaker.

Shoot at the ceiling behind the Earthshaker, and you should discover a locked door, which will open once the boss is destroyed. Take all the weapons and the cloak inside, and dash for the invulnerability outside to destroy the boss.

Whip out your best cannon (the Helix perhaps? or the Gauss if you want.) and your Mega Missiles (don't be afraid to use them, for you'll get plenty later). Keep shooting at the boss (the Megas have a big chance of destroying the small robots around you). Once the boss has been destroyed, you have 2 options:

1) Having not read of this walkthrough before, you go back, and a locked door below the wall has opened. Hit the switch and the wall will open. Go through the red door, and you'll meet loads of robots from the robot makers along the way. IF you make it through (which is VERY difficult) to the end, you will find that the door at the start location has been opened, thus revealing the Exit.

2) Go to the locked door at the ceiling, and you will find that it has been opened. Just fly through the whole corridor, grabbing loads of stuff along the way and finally at the end a wall will open, revealing the Exit, and thus you avoided fighting loads of robots from the robot makers but getting a full arsenal.

Level 4 (Flashing Omega) will be even more hard. Wish you good luck!
