Requiem: Avenging Angel

The game barely functions and crashes often, yet launches and plays on Proton without extra steps. The game is average, the enemies don't play around and there are many power ups. If you're starting this blind then one tip you need is that you need to talk to the barkeep in the beginning of the game to receive a passport. Unfortunately the map design is pretty bad, but the environments are cool. The game has an annoying tendency to spawn new enemies behind you. The boss battles are cancer because they have such a big health pool. If I open the pause menu the cursor is unable to do 360 degree movement, unless I open the menu for power ups, guns and items. The music doesn't play unless you fix it. Yet it's still a pretty cool game. The difficulty curve is odd because it starts out really easy, turns very difficult and turns really easy again once you get the proper rocket launcher and healing power up.

Underrated oldschool-ish FPS. The gameplay itself is nothing to write home about (a few mostly hit scanning enemies, unoriginal weapons, many corridors and a few empty plaza), except for a few innovative powers (including an overpowered bullet time, many years before Max Payne). Most interesting is however the setting (cyberpunk + angel vs demons), with a design both stylish and ambitious: The demons and the bosses, in particular, have stood the test of time and of low-poly count.
