just achivement.. and that's it :D
There isn't any !!!
you get a trophy
Nothing
you get unlimited ammo
you can get a cod6 book at game
For single player, COD6 is longer but is the same in fun as COD4. However, multilayer in COD6 kicks COD4's butt. So if you are asking which should I buy? Get COD6
I don't mean to be rude but. Are you crazy? Cod6 is much better than Lego stars. But I guess it all comes down to what games your into.
You get an achievement called NO-LIFE worth 9999999 gamerscore
you get like...a super solider perk not sure what it give you but i could never find all of them
no
if you get all intel, you get an achievement.
BOOM!
