From Steam's Greenlight Concepts page (sorry about the color)-

Are you fan of RPG games and especially dungeon crawlers? Have you ever asked yourself why most of the dungeon crawlers are set in fantasy worlds and only a few in Space? 
Why not replace a sword with an assault rifle, a hammer with a shotgun, an axe with submachine gun or a dagger with a pistol? 
Why not crawl through huge space ships instead of dungeons, a research base on the Jupiter’s Moon – frozen Europa instead dark forests? Why not fight with heavy robots instead of dragons, aliens instead of trolls, mutants instead of skeletons? 
Take your party of three Space Smugglers and Pirates and explore the secrets of ship wrecks and bases to figure out what is happening in the cold and endless Space. 

Play this revolutionary sci-fi dungeon crawler and enjoy everything you liked in Mass Effect, Dead Space, System Shock 2, Space Hulk, Hired Guns and Aliens movie.
