Description (by MrFlibble)

In the future, a space exploration mission uncovers an alien artifact on Mars that is brought back to Earth for study. The scientists inadvertently open a portal into another dimension and angry aliens start pouring in! Soon the complex is overrun, and it's up to you to fix things, clear all floors of the invaders and shut the portal to their homeworld.

Corridor 7: Alien Invasion uses a slightly modified version of the Wolfenstein 3D engine with enhanced features and a greater variety of monster behaviours. Unlike Wolfenstein, your goal in each level is not only to get to the exit, but also clear the area of all aliens that are present. Some will hide or masquerade as harmless objects, so beware!
