About Alien Insanity

Alien Insanity is a retro-style game set in 2099, after aliens invade Earth. The invaders include mechanical steam-powered shell creatures, bipedal robots and flying eyeball drones. You play a United Nations Secret Intelligence Service agent assigned to guard the President of the United Nations. When a wormhole appears one night and pulls her through, you jump in after her.

Clear each level

Your aim in each level is to kill all the aliens and then find the exit. Each level has a twist, sometimes a literal one.
