Modding

Ok i just got A.V.A and i was curious so i opened its files to see if there was anyway of moding their files like the .rez files in Combat arms. I found the files i was looking for but their in .upk format anyway some of u can find a .upk viewer or something? If u did plz send me the link on where to get it plz and hopefully this wont bring cheap, overpowered, gay mods like in combat arms (super knife)!

omg ? it was just too easy pm me if you want my extractor ^^
tested:
Editing Skin <-- Works fine!
Editing weapon <-- Doesnt popup

So u have an extractor but do u have an injector ? And if u have it just post it here . Do not trust him by pm mayby it's a virus .

the only thing u can mod is the kill signs

YOU CANT DO THAT DUDE =/

Isn't possible at the moment (not that i know of)
