i prestiged once in cod4 before getting bored with it. and no, you do not get anything for prestiging in cod5. each time you rank up you simply get a new rank pic and the flamethrower. but the flamethrower sucks anyway. also, be warned that many people are hosting 3000+ points a kill servers out there so there are a lot of prestige 10 level 65 characters already. BUT, it's still a good game with a great and brutal single player game and a much more crazy almost arcade style multiplayer. to really enjoy it, play the single player on hardened mode then play multiplayer games that have "tactical" in the name. pretty intense.
