Rainbow Six: Vegas 2 is your chance "to rescue America's sexiest city from an escalating terrorist siege that will impose heart-pounding action from beginning to end".
That's what Ubisoft has told us in first details on the sequel, adding that the game "will push the top-selling franchise to new heights with new gameplay features and groundbreaking co-op and multiplayer modes."
Sin City itself has been expanded for Vegas 2, as has the weapon roster available to players with 11 new guns to splatter terrorists with. Team Rainbow's gone shopping in the high street too and bought itself new camouflage, clothing and gear "for the ultimate customizations".
On the multiplayer side, one of the biggest new features is the addition of 'jump in' to co-op. What this means, if you haven't already guessed, is that your mate can jump into your single-player game at any moment and turn it into co-op.
"The single player maps and storyline were created with co-op in mind, meaning every map has multiple entry points and the story is unaffected", Ubisoft explains.
13 new multiplayer maps, two new adversarial modes and an improved matchmaking system are also included.
On top of that lot, Ubisoft is promising the enemy AI in Vegas 2 is significantly improved, and terrorists have new toys to play with too - thermal vision, night vision, and shields.
Accompanying the first details are new screenshots and a teaser trailer, which we've uploaded here for you.
Rainbow Six: Vegas 2 is out on PC, PS3 and Xbox 360 in March 2008.
