So i picked up the classics version of Rainbow six vegas for £15 in the sales and it says in a green box on the back that it supports 2-4 player co-op. Am I right in assuming the green box this means it's an offline feature and the orange ones are xbox live/online features? As I cannot find the 4 player co-op feature I am a little disappointed as 4 player GRAW is great fun with my mates and was hoping to play this game 4 player too!
