So this popped up on the beta server last night it TDM mode. It was kind of ... meh. It's really difficult to see players with the lighting you have, and it's pretty much impossible to tell team colors, so it's just a matter of spawning in and firing down every corridor as fast as you can before you die. It seems almost all of the spawns happen in the center (most frequently up on the highest level). In the center it's just chaos, but if you go to the side areas, there's nothing happening.
