Although this is an expansion pack, this is a classic in it's own right.

User Rating: 9.4 | Tom Clancy's Rainbow Six 3: Black Arrow XBOX
Rainbow Six 3: Black Arrow is a really great expansion pack for the origianal. This of course does not require a person to have the original, but it is still referred to as such. The graphics are not noticeably better the Rainbow Six 3, but they are still impressive. I absolutely love the physics engine that they used. To see the ways in which the enemies fall down dead is so much fun. That sounds morbid, however it is fun regardless. The weapons system was only changed by a couple of weapons. No more .50 cal sniper rifle, it was replaced by the Dragunov. Otherwise it was pretty much all the same. The levels, although fewer, are still a treat. They take the team in another direction, yet still provide some link to the first game. It is shorter, but the XBox Live play does include some of the original maps for fans from the first game. This allowed many of us to sell the old ones since we don't need them anymore. Great. There was also some downloadable content including paid levels. These are great and are also well worth the money. The fact that this game is not as expensive as the first also helps justify the extra cost. Buy this game. I can't say any more.
