SynopsisBehind the bright lights of Sin City lies a deadly terrorist threat. Return as a member of the elite Rainbow Six squad and end the siege for good. This time you're up against new Artificial Intelligence characters armed with thermal vision, night vision and shields. Fortunately, you have a collection of updated weapons just as lethal. Smaller maps put you in closer proximity with the enemy for more intense face-offs than ever. Tom Clancy's Rainbow Six: Vegas 2 also features two new adversarial modes, added rewards and an improved matchmaking system. Leave the gambling for the casinos and don't take chances with the lives of your fellow Americans. Watch the environment change from dusk to dawn and fight through both days and nights. Make your way through new Vegas hot spots upon 11 new multiplayer maps. Updated customization options let you create a character that stays the same in single-player or multiplayer action. In the innovative new Co-op mode, bring a friend in on the action at any time without impacting the story. Select wisely from your arsenal of 11 new weapons, but beware ~ sometimes they won't be enough. That's when you'll need to rely on the intel of thermal scanning and the tactical advantages of leapfrogging. Are you tough enough to see this battle through to the end?
