Grand Theft Auto IV has passed Microsoft certification and is available now. Get ready for the update screen for the next time you boot up the title.A simple patch that addresses two key issues present in the title’s multiplayer component: invisible characters and holes cheaters. Apparently, there was some sort of bug that allowed people to become Kevin Bacon during matches. The cheat code thing, we weren’t even aware of.
Rockstar doesn’t elaborate on its official blog, but it's stated that somehow, people managed to use a cheat code exploit in the component.
If those two things got you down, it’s time to pick up that chin and head back in. "The Ballad of Gay Tony" is hitting quite soon, so sharpen those skills.
