Has been around for quite some time. It's fun, though it can be challenging, because it's not turn-based BT; it's real-time, and one of the things you have to deal with there that you don't here is the timing and speed of your turns and weapons fire, because you try to catch people as they're having to slow to navigate obstacles (or as they land from a jump, when their speed is 0) and you have to deal with weapon recycle times.
