STORY
Inspired by the "hero" shooters of the late 90s such as Duke Nukem, Blake Stone, and Wolfenstein 3D, DOSMan: Space Aliens in Space is a retro FPS game where players take on the role of the titular, DOSMan.
Aliens have invaded Planet DOS, and are wreaking havoc upon the population. It’s up to DOSMan and a colorful cast of hilariously incompetent characters to beat them back and restore order to the once-peaceful planet.
