Damnation - Episode 1 Of Doom

You control a space marine navigating tight corridors and open rooms filled with hostile creatures. The moment-to-moment play involves moving with the keyboard, aiming with the mouse, and firing at anything that moves. Your main objective is simply to survive each level, find the exit, and progress. You collect health packs and armor, swap between a few different weapons, and push forward against consistent enemy resistance. The pacing is steady, and the difficulty feels fair for a condensed version. It feels like a straightforward, functional translation of a larger game into a quick, accessible format.
