Call of Duty: World at War Forum

hey GB, i has a quick question. my friend is coming over and since it's halloween, we're gonna play some nazi zombies. he recently got the map packs for half price and i still don't have them. he really wants to play them here so my question is: will the map packs work if he goes on his PSN account and downloads the map packs onto my hard drive, then we can play on the Zombie maps? i'm just curious.  
 
thanks

@p4ddym1607: great, thanks ^^
