Team Sharpshooter, or any mode where you can respawn is just about running and gunning as it don't matter if you die, as you'll just pop up round the corner in 10 seconds. Team Survival you do have to work as a team, and have to be cautious as when you're dead, you're dead.Vegas is about tactics and teamwork for me and survival is more like CODs running and gunning which put me off COD.
