An odd little platform game in which a mutant army created by Dr. Mangle has invaded Metro City. As Snake Logan, a CIA agent, you have to shoot everything that moves and rescue the citizens. The EGA graphics were already dated when the game was released, but the irreverent dialog is humorous. There are 3 episodes in this game, with only the first episode playable in the shareware version.

Episode 1 - Dr. Mangle's Lab
Episode 2 - The Hidden Lab
Episode 3 - Master Cain
