An anxiety-inducing little torture chamber of an FPS, where you restart every time you die and attempt to progress just a biiit further. No procedural generation here -- waves are set, so like many an arcade-style shooter it's all about managing spawning enemies quickly so as to not be overwhelmed. Easier said than done.

I will say, I don't love constantly dying to things that are behind me (I know I'm probably bad at the game and need to strafe better or whatever)... but man I sure do love almost everything else about this. You start out in a dark room, a lovecraftian tentacle pillar vomits skulls at you, and you're off to fun town for about 90-or-so-seconds before you get ravaged by some other shadowy monstrosity and have to start all over.
