A vacuum level. A large square arena with four large rooms on the corner. The arena though is not open. It is culmination of many hallways that evidently lead down to the middle of the map. Some texture problems when you get down there. A super fast physics model is built in that allows you to go turbo speed along with the fish-eye vision. Got me so swimmy headed I had to wait until it timed out. A minimum of 6 to 8 is needed for this one or you will walk around by yourself for a long time...
