revealed the meaning behind Ms. 'Splosion Man's mysterious "2G1C" feature. As it turns out, it's actually much more innocent than its namesake -- which we will not elaborate upon here -- and simply allows one player to control two Ms. Splosion Men (Mans?) with one controller.
We say "simply," but it's obviously much more difficult than it sounds. One 'splosion lady is controlled with the left analog stick, while the other is controlled with the right. Each character's 'splode function is similarly mapped to either the left or right bumper. See "2 Girls 1 Controller" in action after the break.
