(adsbygoogle = window.adsbygoogle || []).push({}); 1. Have fun
use any gun you like. video games are a hobby and you should have fun with them, if your not having fun take a look at why your not having fun. If you really don't like the game any more it may be time to move on
2. Don't move up faster than your guardian angel can fly
3. Use stun and flash grenades in CQC
many people get killed because their opponents get the draw on them by quickly throwing a flash/stun around the corner 1st
4. USE GRENADES
Yes that means occasional grenade spamming they will kill your enemy and are super overpowered
5. Use UAV this is the most basic and useful kill streak
6. Use overpowered guns
many people say that they're for noobs.
not true even zzirGrizz uses the M21, sandy ravage totally takes avantage of the Spaz12's unlimited range+power. they are in the game for you to use.
7. get a headset
headsets are very useful and 9/10 times you'll hear the troll coming stomping around the corner before he can say 1337
8. use ninja
ninja is extremely useful so you opponents who do have headsets can't sound whore you
9. use commando.
it's in the game, its "cheap" live with it. people complain a lot about it but honestly its not like you can't use it either. the pro version is also good on maps with huge drop offs, afghan etc
10. make sure to buy black ops

Tip 11:
Don't play mw2. It is like a hott chick who pisses you off but you keep her around because she's good in bed. It is a love-hate relationship in video game form. :black:

11:
Everytime you die don't rage and throw your controller at the wall or punch the wall uncontrollably

If someone pisses me off by the way they killed me I just use that method to piss other people off. Your enemy will make more mistakes when angered :y:

12. dont kill your cat when u die

13: dont then eat the cat instead feed it to your enemies :p

14. Buy Black Ops then throw this shit away.

15. Don't even think about arguing with the 10 year olds, mute them.

16. Don't boost.

17. when you play FFA spectate them first to see if theres boosters then when you see a pair get your at4 or rpg out and shoot them at their face.
