Rainbow Six Vegas 2. Campaign is largely fantastic, controls feel great. Teammate AI is largely good, they actually shoot people (unlike most FPS games where they just make up the numbers) but occassionally get stuck and refuse to move. The one stealthy solo mission was gash. The plot isn't really explained at all well so I've no idea what the point in most of it was. :/
Favourite moment of mine is rapelling down an elevator shaft, hanging upside and using a silenced pistol to pick off a guard. This attracted a fellow guard's attention, but my squad burst through a door behind him and killed him. :lol:
I imagine split screen to be good fun, but online isn't anything special. And I've just noticed I've made a list of points with zero cohesion.
