A few technical details:
1. Because of the way the wiimote works, each player will be limited to one position, and we can calibrate accurate fire from that position. Moving your position (and therefore your actual aim point) COULD be tracked with the kinect, but I'm placing that outside the scope of this game. Instead, the players will stand behind a short divided barrier that they can duck behind, but it will limit lateral movement.
2. All human targets will be billboards (although some may be animated). Using MD2s or another 3D format would be amazing, but we'll save that for another project that doesn't have a hard deadline.
Here's a sample screenshot of one potential arena (I hope to make a few arenas, and didn't you ever want to do this at work?) and since this is my first foray into the Kinect, I have a screenshot of the Kinect's capture of me alongside a depth map of the same scene. You'll need a few libraries to get this up and running in Linux, I'll leave details later.
