Co-op

From Binding of Isaac: Rebirth Wiki
(Redirected from Babies)
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 2 player local co-op on PC. The Afterbirth DLC increased this to 4 player local co-op. The Playstation 4 version of the game is capable of both local and online multiplayer via PS4's "Share Play" feature. (The Playstation 4 version can also support up to 4 players.)

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, except for certain special babies like Magnet Baby and Isaac 2.

Added in AfterbirthJoining as a co-op baby will bring up a menu that allows the player to pick from 5 special babies. Dying as one of the available special babies will remove it from the pool.

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 co-op 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 Scapular
    Scapular Icon.pngOnce per room, when Isaac is reduced to his last half red Heart, the aura around his head temporarily vanishes and he is granted one Soul Heart.
    .
  • Because at least 1.5 hearts are required for co-op, Player 2 cannot join when playing as The Lost.
  • On the Nintendo Switch, you must restart the game after setting up the controllers or the join button will not work.
