You move just like any other shooter, by the GRAW PC movements, you mean the whole view bobbing, and stuff right? If you have played RVS, you will notice that you move a lot slower in R6 Vegas, but the teammate AI is excellent, they hold their own very well, sometimes they even kill more Tangos than you. Its a big change from the previous R6 games but I like it, I have been playing CO-OP Story since I bought Vegas, and its a blast.
