It's a tactical, squad-based shooter. It requires you to lead teams in different directions and depends on a specific play style. If you really need to know, it takes two seconds to YouTube it and watch footage.
It's not anyone's job to spoon feed something simple to you.
I think you're confusing this with SOCOM's 1-3 :) --> Those games were acutally about stealth, tactics and controlling a team. This game looks like an average shooter that's made to be accessible to everyone which is proven by the inclusion of move controls. Its time for people to admit SOCOM sucks now and has gone casual, which is sad because SOCOM 2 was about as hardcore as a game got and I loved it.
