Players have discovered a serious glitch in Gears of War 3, that is reportedly freezing Xbox 360 consoles. It occurs while trying to enter a horde match in split screen with two different gamer profiles. Not only will the console freeze, forcing the player to restart their console, but afterward one of the profiles will be altered, prohibiting that player to enter a match. The "loading game mode" screen is when the glitch appears to be happening.

Those looking to play multiplayer are best off waiting for a patch or heading online in the meantime.
