2- 5 Man Squads with slower health regeneration, a bit longer spawn times "TO ENCOURAGE TEAMPLAY AND STAY OUT OF THE SPAWN LOBBY". Reviving and healing your teammates is faster, so throw those med packs and watch for downed teammates. Body shots do some damage but suck your ammo, go for the Head it's quicker, saves ammo and helps improve your accuracy ! You will find this game play much more brutal so keep your head down.
