Unlocking this character is the most complicated of all (not counting The Lost pre-DLC), with secrets piled onto secrets. The Forgotten does more damage and starts with two Bone Hearts, which take three hits to deplete, whilst The Soul only has a single Soul Heart. When playing as The Forgotten, players will be controlling both that character and The Soul. The Forgotten is perhaps the strangest of all the playable characters, as it is actually two characters.

The Lamb is a secret boss that can only be reached after defeating Satan five times whilst holding The Negative item.Īlternatively, if the player has enough hearts, hurting themselves on the spikes in a Sacrifice Room 12 times on the same floor, there will be a 50% chance that the player will be immediately teleported to the floor where The Lamb awaits. Sounds simple, but unlocking the Missing Poster requires defeating The Lamb whilst playing as Isaac. Players must die in a Sacrifice Room whilst holding the Missing Poster item to unlock it.
