"Together [with Double Eleven] we are working hard to give the mobile players exactly the same experience the PS3 players have had on the living room TV," PlayDead founder Dino Patti told us back in March.
Update: Playdead's confirmed dates were out by a day. We've updated the post with the correct release dates. We've also corrected the North American price.
