Thanks for the info but I updated already. Couldn't be bothered until something happens for real, then if I have to I'll buy another used Wii u. Now to play Nuketown, my favorite BO2 map. Played it on the PS3, loved it.

I kinda agree, also since both hacking teams (Chadderz & Marionumber1) probably won't let people have/ use cheats or loaders how it seems. I'll wait though and not play online.
