I got this game for about $7 by accident. At least I didnt waste a fortune.
The guns are fun to shoot and the missions are fun to play when there's nothing else to play or do. A problem that really puts a stop to the fun in campaign is the spawning of enemies. You can clear out a court-yard so you can safley escort your rescued hostage to her husband, but when you get back there's more guys shooting at you....BUMMER!
Graphics arent anything special either. Also, the character movements and the way they look are just kinda weird, in an unnatural kind of way.
Rent it....but if you want a good Rainbow 6 with the same good elements and fixed bad ones, get Lockdown. By far the best in the series.
