Ubisoft has released a multiplayer demo of Rainbow Six Vegas for the Xbox 360 - available now on Xbox Live Marketplace.

At 985MB the demo is a bit on the heavy side, but you are getting to play what could well be the multiplayer game of the year. Players will have access to Attack and Defend, and Terrorist Hunt modes.

Attack and Defend revolves around a bomb placed in a casino, and Terrorist Hunt requires four players to team up, working together to take down the terrorists.

As we reported earlier this week, the game is now being released on December 1, and not on November 24 as was previously intended. You'll also be able to purchase the PC version on the same date. A PlayStation 3 version is due at the launch of the console in Europe.
