Xbox 360's crown jewel of the Fall, Gears of War 3, isn't without its flaws. The game is reportedly causing freezing issues, forcing gamers to restart their consoles. The problem seems to affect the "loading game mode" screen when player try to play Horde 2.0 split screen with two gamer profiles. After the error occurs one of the player's profiles will be altered, keeping them from entering another match.
A "Super Moderator" on the Epic forums has heard the cry of pain from Gears gamers. While Epic seems to be aware of the problem, they are still trying to find it's source. A fix has not been issued.
This is definitely a bummer for gamers, like myself, who often play local co-op. If split-screen is your mode of choice, you might want to hold off until this issue has been resolved. We'll keep you posted.
