Based on the Wolfenstein 3D engine, with a similar level of graphics and sound. In 2012, a mission to Mars returns a mysterious object to Earth. A dimensional gate called "the Vortex" opened up and an alien invasion force entered the maze-like research facility known as Corridor 7. Naturally, you want to defeat the invaders by killing them with various weapons. Computers sometimes require access cards to get to other areas, and there are health stations where the hero can recharge. The full version came on floppy disk and CD-ROM, the latter having extra levels, weapons and enemies, and added multiplayer play and CD audio. There are over 40 levels in the full version.
