Looking at the video for BF:2142, its obvious the shit is just a reskinned BF:2 to compete with ET:QW.
The problem is, ET:QW looks to do futurisitic combat so much better than BF:2 was able to - and BF:2 owned my life for a long ass time. But Quake Wars has one thing going for it - ET:Wolfenstein being ridiculously bad ass.
