Solid FPS action and interesting weapon power ups with a great look! The only issue is that that performance is very poor even when I keep it in a small window on a pretty powerful computer. I think all of the cool simulations, which I LOVE, are not very optimized so it was difficult to play through too much of it. There were also issues where my camera would get swarmed with objects where I could see and then I would get y33ted into outer space when I would use an explosive weapon. Still really enjoyed it, but I could have explored more of it if the performance was better.
