Deep beneath the smog of a plausibly denied planetoid, there lurks a space hulk full of dessicated hand monsters, shorn dreadlocks and long-emptied Pulse Rifles. The vessel mostly lies silent, but every so often, an ancient server deep within the core crackles awake, beaming an ominous signal far out into the void, and the chitinous corridors come alive with flamethrowers and squelchy stabbing noises and oh, so much screaming. Also, the coveted chirping of Steam achievements.
