Bio Menace

The CIA has learned that gigantic mutants are wreaking havoc in Metro City and their sources say that the destruction is caused by a scientist calling himself Dr. Mangle. For this reason, they send Snake Logan, the CIA's top secret agent, on a dangerous mission: fly over Metro City, investigate what’s going on, then report back to the captain. Unfortunately, Snake’s plane is shot down, forcing Snake to walk the streets and kill mutants.

There are three episodes in this game: In “Dr. Mangle's Lab” and “The Hidden Lab”, Snake must destroy two labs and Dr. Mangle himself. Just before he dies, Mangle tells him that he is forced by somebody known as Master Cain to do his bidding, or he would be killed, so in “Master Cain”, Snake sets out and destroy the creator himself.

All three episodes use the Commander Keen engine, which id Software used. It has a similar score box located at the top-left of the action screen, same menu system, same on-line help, and the same start-up screen where the game detects your sound card, video card, I/O devices, and the amount of memory you have. It even allows you to view the old status screen if you press [Space] during gameplay.
