Not sure if this has been posted yet I havent seen it. Basically what they said is that it suck but PEC mode sick. Bad story, boring sniper games, etc. They said that its really only good for multiplayer which only hits about 10% of the xbox community so its not very impressive. I'll tell you what they have in their little plus minus list.
+Persistent online multiplayer mode rocks.
-Generic, been-there-done-that single player mode.
-Lame story, dialogue, and cutscenes
? Will the real Rainbow six ever come back again?
