1. Never shoot an enemy, then chase them, because all they have to do is hide behind the next corner and kill you. 2. Only take the shot if you know you will hit your enemy. 3. When killing someone, aim for the feet because the recoil will kill and it gets those noobs with final stand. 4. If your fighting an enemy and they have the advantage, bug out and find a new targer, don't just stand there and get shot. 5. If fighting an enemy at long range, move around alot, do a little dance...but keep shooting!
