E3: COD4 beta 360 exclusive

The multiplayer beta test for Call of Duty 4: Modern Warfare will be exclusive to Xbox 360.

Bigwigs at developer Infinity Ward - Grant Collier and Jason West - announced the news earlier this morning, after giving an in-depth demonstration of the game at Microsoft's E3 conference.

And what a demonstration it was; using a limited palette and liquid animation to produce a coherent effect that looked "properly amazing", according to our man on the ground, Tom Bramwell.

"We're making a more sophisticated, deeper Call of Duty experience," Infinity promised on stage, and the evidence was certainly compelling.

There's no word on when exactly this beta test will be taking place, but we expect more information and media to spring out of E3 later this week.

Call of Duty 4: Modern Warfare is due for release on PS3, Xbox 360 and PC later this year - coinciding with Peter Moore's promise at the conference that all games shown will be out before the end of 2007. Only Resident Evil 5 broke that exception.
