Co-op

From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search
Disambig.png This article is about co-op babies. For the monster, see Baby. For items that follow Isaac, see Familiar.

Rebirth features two player local co-op on PC (Up to 4 with the Afterbirth DLC), while the Playstation 4 version is capable of both local and online multiplayer via PS4's "Share Play" feature. The Playstation 4 version can support up to 4 players with the addition of more controllers. Co-op players can join in at any time as a random baby, taking a heart container away from Isaac and giving it to the second player. Subsequent pressing of the join button will despawn the baby, giving Isaac the heart container back.

Babies share Isaac's stats except for health and damage; babies deal half of Isaac's damage. Babies always have flight, but they cannot interact with objects like items and pickups.


 PS4  DLC Indicator.pngTo bring up the special menu on PS4, the co-op player has to simultaneously click either left or right on the d-pad and the options button when joining in. It might take a couple tries because it does not work every single time.


 PC  DLC Indicator.png Upon joining, co-op players have the option to choose from a pool of 5 special babies. When one of those special babies dies, it is removed from the pool. Once the pool is depleted, joining will cause the co-op player to spawn as a random normal baby.

Notes

  • Soul Hearts will be given to Player 2 before normal hearts, and half hearts will be given before full hearts. If player 2 dies, they can rejoin the game at the cost of another heart container, as a new random Baby.
  • The appearance of a majority of the Babies is solely cosmetic, but there are a number of "special" Babies with beneficial effects. However, some special babies have detrimental effects.
  • The last shooting familiar Isaac picked up will follow Player 2 instead of Isaac.
  • If Isaac has more than 6 total hearts, including soul hearts and black hearts, Player 2 will take two hearts instead of one.
  • If Isaac has the maximum of 12 hearts, including soul hearts and black hearts, Player 2 will take three hearts instead of one or two.
  • The maximum amount of hearts Player 2 can have is three red hearts and one soul heart, using Scapular.
  • Because at least 1.5 hearts are required for co-op, Player 2 cannot join when playing as The Lost.
