It's been revealed that the Xbox 360 version of forthcoming RTS Command & conquer 3: Tiberium Wars supports the console's Xbox Live Vision camera in online multiplayer.
Basically, you'll be able to see your opponent's face - and they yours (if you both own the camera obviously) - during Live battles. Plus, it's also mentioned that the battle winner gets to make use of something called Spotlight cam, which it appears is 10 seconds worth of visual humiliation-giving to your enemy after a fight ends.
Further details on C&C; 3 on Xbox 360 can be found in our recent preview.
