I read in IGN's (I think) preview that there was a split-screen co-op mode. I have the retail version and haven't been able to find it. The only multiplayer options seem to be xbox live and system link - no split screen local co-op game play... tell me I'm missing something!
I loved playing the last SC with my brother and I on the same team, basically playing the single player game with the both of us...

This has been the major dissapointment for me with this game. Chaos Theory was awesome playing the co-op missions with a freind but the co-op in this version just seems to be the multiplayer capture the flag type game Well gutted. I really cant beleive they have left out the co-op SP mission side of it.

I cannot beleive that they left out propper co-op missions either !!! IN chaos theory they were friggin excellent !

This downloading data is just crap. You cant even shoot the guards.

I hope they release an update with some FULL co-op missions !!
