An excellent game that I would reccomend to almost anyone.
The co-op is fun and tense, the single player is brilliant and again, very tense. In games like Halo there isn't much tension but in Rainbow Six Vegas, opening a door could result in a blood-red screen, resulting in a controller-smashing wrath. Evidently, the game can be frustrating at times but that's only if you don't maneuver in a significant way or take the correct precautions. Just make sure you use other ways and routes to execute what you need to achieve. You'll be so proud when you get achievements, when you pass levels and when your character upgrades on the magnificent, engaging Xbox Live plays that you will most probably invest in the sequel. I haven't. Yet. I sold this game...
It is brilliant, though. I mean that. Buy it.
