From the Review: "RSV features all of the classic multiplayer modes and a great mix of old and new maps that will keep clans and lone wolves striving for medals well into the next year. The best addition in the game, though, is without a doubt the four-player co-op. You and three of your friends can now experience the entire single-player campaign together as one Rainbow Six squad. Note to game developers: Every first-person shooter should feature this mode from this day forward. The only way Ubisoft could improve this mode would be to include the story elements, which it inexplicably cut out.
Fans of Rainbow Six, and first-person shooters in general, should not miss this game. As a co-op experience and as a tactical shooter, Rainbow Six Vegas sets a new benchmark for the gaming industry."
