The developers of popular little horror game Binding of Issac have slowly been trying to release the game of its original flash build, which has proved to be restrictive enough to need to go resulting in what has been called Binding of Issac: Rebirth. Along the way they’ve found the time to make the graphics 16-bit and added other new things, including a co-operative mode.

The co-op is local and sees Player 1 as Issac (or presumably one of the other playable children) offer up a heart to a friend who then spawns in as a floating fetus-like baby, randomly assigned with any number of different skills and stats. So it could be useful or it could be a hindrance, you just won’t know until you spawn in Player 2.

Below is a video by the McMillens as they demonstrate the co-op in a procedurally generated challenge dungeon. It obviously can’t show off everything but we do get a good look at the basic mechanics and of one of the Player 2 skillsets – a bomb spawner that plants random bombs about the room that can’t be controlled by the player.
