If you have not seen the videos they are below
My opinions of the videos is that I am amazed. It looks and seems to play like SWAT 4 but is loads better. Information I gather from the videos is that in singleplayer your teammates have their own individual voices. In one vid you can hear Eddie Price talk with his british accent. It looks very similar to SWAT 4 when stacking on doors as your team mates get into position. One of the things i notice is you can actually run and shoot rather than SWAT 4. It looks incredible and I cannot wait!!
