Freezing Wii's has usually been something that happens to those of us that get host duties. The Wii doesn't have enough resources for a game like this and can lock up occasionally. I have heard others say they all had their Wii freeze at the same time in the same match. It could be a hack but someone else pointed out that there is a glitch that may allow this to become possible. Either way, it's just yet another reason to find another game to play as this one has gone down the sh!ter
Yes as Noah said its a glitch. Very easy glitch and i know how to do it but i never do it because its damaging wii.
If someone like Dazran or someone else post this on youtube then its gonna be a Major problem.
Good thing is that Treyarch knows about this and they will put it in the next patch which IS coming.
If not,then they will fix it in hotflix but this glitch works also on xbox and ps3 too.
