If you havent already started the online,keep your prestige tokens untill you prestige,you can use them to unlock weapons so you dont have to rank up and unlock them again,i had five tokens and wasted them,i was only able to unlock one weapon when i prestiged instead of 6!
Carlo thats not on ps3 for sure,when people get use to the maps they antisipate (sp) were the enemy is without a uav,i do it all the time and get kills
