Bio Menace Episode Two Secrets

The Bio Menace Series runs on a modified "Good-Bye Galaxy" engine. There are no glitches. It's modified!

If you hold down the keys C, A, and T, then you will get the machine gun with 90 shots, and 99 grenades.
In Corridor, get the secret level bonus gem in the hidden wall just above the exit.
In Ant Town, hop on the first "fallable" block and jump off near the bottom of the level. The secret level bonus gem is in clear sight above a cave/door thing.
In Specimens Lab, there is a secret area above the main level. There is a key up there, which is used to unlock a door up there. Inside you will find some good friends ( Duke, Yorps, Boobus Bombs, Apogee Folk ). But who needs friends? You can have more fun by shooting the Apogee Folk! Be sure to get the secret level bonus gem inside the room, too.
Also in Specimens Lab, there is a "vicious, mutant" Yorp!
The level after the Queen Bee ( the Queen Bee is after Ant Town ) is a junkyard/scrap metal place, if I remember correctly. The hostage in this level is Commander Keen.
Don't forget the bomb in the genetics lab. Don't forget to plant the bomb after killing Enforcer. There are two endings to this game, depending on how you use the bomb. I recommend collecting and planting the bomb, but others may disagree.
Hold up until you hear a noise. Press "fire." This is a cheat for a plasma bolt. Nice weapon, but it takes one point of damage from Snake.
Turn left and right six or seven times and press "fire." This shoots out six fireballs, three in each direction. I can rarely get this to work, but maybe you will have better luck.
Turn left and right six or seven times and press "JUMP." This gives you an electron shield. If I remember correctly, this makes Snake look like stone and only lasts a second or two. I can't usually get this code to work either.
Hold up until you hear a noise. Press down. You will be invincible for a few seconds.

That's all I know. If you know of another one, e-mail me.
