Complete Walkthrough of Secret Level 2 (Megas)

This is not a difficult level in my opinion, for there are plenty of assistance to kill the boss and many power-ups to boost your Shields.

First you see a red door, and the red key trapped by a locked door behind. Immediately watch for Canaries coming from the top, and of course an Omega Guppy which drops Smart Mines. Having the Canaries destroyed, proceed and destroy 2 Spiders (and their spawns). Then move on and you should see a Phoenix Cannon behind a force field. Shoot the switch you see, and this unlocks the door at the red key from the inside.

Go out, and two walls will open, revealing 2 Mini Bosses. (Watch out for their Fusion Cannons!) Kill them and shoot the switch at the left. Go back to the force field, and you should see a wall has been opened. Shoot the switch inside, and having the force field deactivated go in to grab the stuff (1 Phoenix Cannon, 1 Headlight and 2 Mega Missiles).

Whip out your Phoenix Cannon and head for the start position. Shoot at the door and immediately fly up to prevent shots from coming back at you. With some luck you should get the Phoenix into the door and then bounce back, opening the door. Go in to grab the red key, and this will be the first and the last time you can access to this exit, for the door will be locked on both sides as soon as you pick up the key.

Go back to the normal level and SAVE GAME. Head back to the teleporter again.
(That teleporter can only be used once for the door will be locked on both sides once more when you enter that teleporter.)

Use your best cannon (in this situation, the Helix) and be ready to meet LOADS of robots inside the boss room. Use your Mega Missiles also, for you'll have little chances of using them later on. Once you have entered the boss room, shoot at the light above, and the wall blocking the invulnerability below is opened. (By the way, the red door is locked from the inside, so you cannot open it. Also, once you enter the red door, a wall above will your start position will close, giving you no escape to in-coming missiles.) Take it, and dash outside, and eliminate as many robots as you can in the shortest amount of time. A Class 2 Supervisor Robot patrolling drops an Invulnerability. The 2 Omega Guppies which drops Smart Mines leaves 2 Mega Missiles each. The Mini Boss on the left drops an Invulnerability while the one on the right drops 2 Cloaks. With the sufficient power-ups you should be able to take down the boss.

And finally, having the boss destroyed, the two doors at the blue texture on the walls on the left and the right of the room is opened. Go there, and zoom straight down the tunnel to get all the power-ups (2 Vulcan Ammo, plenty of Energy and plenty of Shields) and some hostages (Watch out for the Mines!).

After that, go to the door at the top of the pillar at the other end of the room (it is opened once the boss is destroyed). Kill the Driller, and proceed. Grab all the power-ups. You may have discovered that there is an Extra Life behind a locked door behind you. You cannot open this door yet, for the door is locked on both sides.

Once you have reached the end of the tunnel, look up. You should see a room has opened and a TRN Racer inside. Kill the TRN Racer, and use your Phoenix to try and hit the switch on the floor of that room. Once you have hit the switch both force fields will have been deactivated. Go in, and just before you exit a wall will open on your right, revealing some shields and a switch. Shoot the switch, and the door of the extra life has been opened. Afterburn there, and another wall will open, revealing yet another extra life. Grab it, and shoot at the switch on the floor so that the door is now unlocked (from the inside). Dash back out to the Exit.

You're done! It wasn't too hard, was it? Keep your eyes open for Secret Level 3...
