Today, players with access to the Gears of War 3 multi-player beta will have the chance to test the Big Head Mode feature. Gamers who play as COG or locust will have heads that are four times the usual size. In addition to their swollen craniums, the characters will also have extremely high-pitched voices. The Big Head Mode will be available when Gears of War 3 launches on September 20th. Big Head Mode is always fun in games, so if you have the beta, be sure to let us know what you think!
