This is a really great and challenging shooter that seems to take heavy inspiration from Quake, i.e., brown. The enviroments are much more detailed and "realistic" than anything you'd find in Quake, and there is an insane amount of enviromental interaction. I found a piano where you could interact with each key individually with each one playing a different note, and you could change the tone of the piano to give it different sounds. You can shoot out most lightbulbs, read random books on the floor, flush toilets, break most items to find ammo, it's incredibly impressive and I love how much attention to detail there is in the world. The enemy design is amazing with each enemy looking incredibly distinct and a lot of them seeming a bit off in what I'm sure was a purposeful way to give them more janky retro charm, for example, the grenade launcher guys almost sound like pigs which is weird but it's very distinct so you always know when one is around. If you like retro style shooters you have to play this game, I'm not far into it but I'm guessing it'll be up there with Dusk for me as a great modern retro style shooter.
