Once you beat the big badasses and clean out the moon base you're supposed to win, aren't you? Aren't you? Where's your fat reward and ticket home? What the hell is this? It's not supposed to end this way! It stinks like rotten meat, but looks like the lost Deimos base. Looks like you're stuck on the shores of Hell. The only way out is through.
To continue playing, you can play The Shores of Hell and its sequel, Inferno!
