Just following up in case anyone reads this in the future. The game is really good. In FPS games muzzle flash obscures the target and there’s a little of this here, and there’s a rhythm to shooting enemies and then stopping when they are dead so you don’t waste ammo. Once you get used to it, it feels like a challenging part of the game. I didn’t find the map key until like an hour ago and I wandered around a lot looking for the next thing. Navigating is a large part of the game, because exits and tunnels are not always obvious. Sometimes it’s irritating especially if you don’t use the map. Movement and the world are awesome
