if anyone has, it'd be evan
Not sure. I know people modded the actual game of World at War for zombie 'enhancements' but from my knowledge nobody has done it to Black Ops yet.
zombies for now can be modded with a jtag but we need kv to go online so zombie mods will cost $
wait till modded iso s come out then it should be fun
EDIT: i just watched a live stream of some kid with USB mods he had unlimited ammo and godmode on
USB modes should be here soon
