Go through the prestiges.

First Prestige and gooing for high in the world

Play HQ and S& , maybe if can get a crew together , then some power level too.

I will go to 10th prestige by playing SnD HC then play HQ for finishing all the guns

Well play search and destroy and use the same tactics as COD4!

My tactic isnt up there, Which is rank to 10th Prestige whatever way i think is best.

Well, First im going to like play Team Death match until i unlock head quarters and search and destroy (don't you unlock them at the same time lol or something). Then depending on how good they prestige symbols are i might prestige. If there good im going to go all the way too 10 and then max out my guns , like unlock everything etc.

I think my first match will be team deathmatch (ofcourse) and trying to snipe and just get used to the game first

None of the above. I'll be using my favorite gun not a cheap one *points to mp40 and m16*. Hmm ill also be exploiting glitches and ps quitting but ill never stoop to the level of a person using a cheap gun.
