1. Best thing to do for those people with the power weapon is to get help from your team mates to kill him, if you put a couple shots on him before he call kill you then you are doing a great job, just be sure to call out to your team mates that the person with the weapon has shots on him so he knows he's weak and easy to kill, if it's a lone wolves game wait for someone else to go after him and when he least expects it shoot him in the back.
2. The longer you play the harder it is to rank up, and to be good you need to play alot of games so there really isn't much you can do, oh and by the way I think the number beside my name is stupid and I really don't care about it because I'm a 47 but I poop all over 50s

3. I play halo, I'm telling you because you can practice with me, you will be negative 5294 when I'm done with you.
