For which game? BO? I highly suggest you not to get the 1st Map Pack that Treyarch made for BO, I like to maps, Kowloon and the other non-snowy map (forgot the name). I disabled the pack cause I kept getting the 2 snowy maps which I hate. I suggest you get the latest map pack (not the Zombie one) (if you love Zombie then go ahead.) the one with the map called Hanger.
I do not have the map pack but ive played it on my bro's girlfirend brother xbox and I really liked it, if win the 1600 MSP for xbox ima get that mpack.
