Ubisoft today announced that Tom Clancy’s Rainbow Six Vegas for the Xbox 360 has gone Gold and that it will be released on the 1st December in the UK. Rainbow operatives take to the chaotic streets of Las Vegas as an escalating terrorist siege in “Sin City” threatens to take world terrorism to new, uncontrollable heights. The future of global security hangs in the balance as you battle to defend classic Vegas locations and environments like Fremont Street, the Strip and casinos. A Multi-Player demo has just been released on the Xbox Live marketplace, featuring two gameplay modes (Adversarial: Attack & Defend and Co-op: Terrorist Hunt) and one map (Calypso Casino). Adversarial modes will hold up to 16 players and Co-op modes will hold up two four players on Xbox Live or System Link.
