Here's the E3 Trailer:
The game is about two brothers that have to venture across dangerous land to get a cure for their ailing father. You, as the player must control both brothers, Big and Little, simultaneously. You control Big with the left stick and left trigger, and you control Little with the right stick and right trigger.

Justin McElroy wrote:Brothers tests the limits of what games are capable of communicating and, in doing so, strengthens the medium as a whole, if only a little. The game's final moments moved me to tears in the act of pressing a button. Not because it triggered some heart-wrenching dialogue or sorrowful music, but by the implications of the mechanic itself. I'm not sure there's a better compliment I can pay or a better indicator of how important of a game Brothers is.
