Changes

This page documents Antibirth's changes to Rebirth's content and its expansions.

Characters

The Lost

• The Lost now carries the D4, the Holy Mantle, and has spectral tears, without the need for Afterbirth and its unlocks.
• The unlock method for The Lost has been changed to the method in Afterbirth, which is dying in a Sacrifice Room while holding the Missing Poster.

Eden

• Eden no longer has variable luck. Instead, Eden always has their luck set to zero. Because of how Rebirth handles Eden luck, being revived as a different character doesn't change luck, even if the character was Eden.

Dark Judas

• Most costumes now have unique Dark Judas variants, improving how the character looks when many collectibles have been obtained.

Pickups

Black hearts

• Black hearts have a different sound when picked up.
• Bigbook animation has been replaced with a screen shake and black particles that fall from the room's walls.
• Monsters disappear in a black smoke.

Bombs

• Bombs' detonation time is slightly increased.
• Fuse now has a lit appearance, and emits a small amount of light.

Items

D12

• D12 is featured as a new item, without the need for Afterbirth.
  • Antibirth's D12 has the same effect as Afterbirth's D12 merely by chance, both developers came up with the same idea independent of each other.
• D12 has a new sprite.
• D100 activates D12 as well.

Other items

• Book of Belial has a new animation.
• Poop created by E Coli is not axis-aligned, but is now similar to a normal poop.

Monsters

• Champion enemies have improved coloring.
• If a Clotty comes into contact with fire (i.e from a fireplace), it will turn into a Grilled Clotty.
• With the Book of Revelations, you can get 2 Harbringers in the same chapter, allowing you to more easily unlock the Super Meat Boy/Super Bandage Girl achievement. Alt stages might be a factor in whether this happens, it might be only one Harbringer per stage alt. (Ex: Famine spawning in Basement 1 and Famine spawning again in Cellar 2.) Possibly a bug.

Rooms

Sacrifice room

• Sacrifice Rooms now have an alternate backdrop with blood on the floor and walls.

Devil Deals

• Taking a 2 heart devil deal while you have one red heart container will cause your character to lose all health.
• Running out of red heart containers to spend will cause all other devil deals to turn into soul heart devil deals, like in Afterbirth.
• Soul heart devil deals are sometimes offered without having any red heart containers, like in flash TBoI.

Technical

• Improved lighting effects.
