1. aim for the head.
2. actually talk to your teammates.
3. don't hog all the power weapons.
4. if someone is better at you with the sniper, let them take it.
5. don't complain if someone takes your kill, they're just trying to help the team.
6. don't tell everyone what to do.
7. if you're losing don't quit the game because you can have a comeback
8. in skirmish it's not all about kills so don't complain if some people don't have as good a k/d as you.
9. if you're winning then don't go out because you don't need to give them any kills, and you can just wait the clock out.
10. learn the names of important places on the maps
11. if someone is chasing you, run around a corner and toss a grenade at the wall. chances are the other person will run into if and lose their shields giving you an easy kill.
12. don't trash talk if you lose, just say good game.
13. don't trash talk if you win, just say good game.
14. the exception to 12 and 13 is if the other team tries to start a fight in which case you should defend yourself.
15. have fun.
I think number 5 shouldn't be up there because it is a worthless tip. It doesn't help you get better. In my opinion you don't deserve a win if you have to keep suiciding just so the other team can't kill you. Real players will either quit because its not worth staying if the other team has full control of the map, or just play it out.
other than that it's a good guide
