I wrote this in 2 days using MSVC 6, SDL, OpenGL, and FMOD. It is a Mutant Storm/Robotron/Llamatron inspired shooter, just try to survive as long as possible. My personal best is less than 5 minutes. Perfect for coffee breaks or just to clear your head. It's freeware, so share as much as you like. Available in many PC flavours. All feedback welcome!
