Treyarch, who developed CoD2 BR1 for original Xbox, has delivered an impressive game. Everything has been ramped up, graphics especially. There are some noticable glitches: i.e. characters vanish after a certain distance, bodies get stuck in walls, but overall everything flows very smoothly. The new things that really shine are the destructable cover and the incredible class-based multiplayer. Words don't do the hectic 24 player War mayhem justice. You have to play it on LIVE to truly appreciate it.
