A solid retro FPS, somewhat reminiscent of Quake with the enemy count cranked up to 11. The movement is fast and satisfying. There is a nice variety of weapons that all feel good to use. The enemy variety on the other hand is a bit lacking, despite technically having several distinct types they all act more or less the same aside from a few outliers. The biggest downside is the level design, in most cases it's just... not really there, but it doesn't detract from the core gameplay of mowing down enemy hordes too much. It's rather short, but it doesn't overstay its welcome and there's an endless arena mode with several maps if you want more action. Definitely worth checking out.
