Gears of War 3 fans have discovered a glitch in multiplayer mode on the Xbox 360, which locks them out of their account unless they delete their profile.
The problem arises when people are playing Horde 2.0 via splitscreen in co-mode. When this happens, the glitch makes one account permanently void. Thus, making it impossible to login to any match. Epic is aware of the situation.
Epic games replied “Getting this resolved is a priority for Epic. We are collecting information internally, sourcing as much as possible from the community and exploring potential fixes. We do not have any recommendations to share with players just yet.
