The level design is bland just like the other campaign. Some panic events abruptly stop after second to third wave. health items placed outside the safe room which is odd, you can easily miss it because our minds are stuck with health items inside safe rooms. The finale is pure hell to bots. I have played this a couple of times and even on easy mode, bots still can't reach the helicopter as if they all have trouble going up. The ending shows a camera and a helicopter fly out of the map exposing one missing textured room we are not supposed to see.
