Isaac Cheat Sheet

Co-op Babies (Rebirth)

One of the new features added to The Binding of Isaac: Rebirth is local co-op multiplayer, where the second player controls a floating baby. It works in a drop-in/drop-out style of play where the second player steals a heart container from Isaac upon spawning. Damage is lowered to balance things out but every aspect of Isaac's items are copied over to the second player's baby.

Every time you spawn in a new baby it is randomly picked from one of the babies in the HUGE list below (There are 203 in total). Most of the baby skins are cosmetic, however quite a few also have their own special abilities.
