Dead Shell

You're commanding a die-hard assault squad. Destination: Plutonia, a settlement on a Doom-4 class planet. Shuttle cargo: a range of lethal weapons, from axes and chainsaws to blasters and BFGs. Anything might come in handy in Plutonia, the Federation's most remote colony. Scientists, miners, guards – all sorts of civilian personnel worked there until recently. A week ago, the Center received a mayday signal from the settlement. Demonic roars and screams of terror filled the comm channel, and then it fell dead silent. It's time to descend into the infernal abyss and show the demons who's the boss here. Fight your way through all the circles of hell to reach the very bottom. Look cosmic evil in the face and emerge victorious.
