Aardwolforvark is right! The perks are almost ALL from MW2... Just given new names, requirments and sometimes effect... But these are mostly from MW2 :(
@taymour117 Dont be a idiot! All the lvls are possible, if its too hard for ya, check the walkthrough...
Cou,d do with some work, still a great game... Ill give it a 7/10...
Make another one!
