great atmosphere but that's the only good thing I have to say about this. The most frustrating part was how the gun only fires when it feels like it. the fire rate has no pattern at all. I'm clicking constantly in hoping that a blaster bolt will fire. also I am able to beat the game every time by simply backing all the way up and letting the zombies glitch themselves into a pixelated heap. one or two might be able to get through but somehow the terrible gun play somehow allows me to take them down if Im lucky enough that it will actually fire something.
