The Binding of Isaac: Rebirth (Windows)/Afterbirth+

This is a sub-page of The Binding of Isaac: Rebirth (Windows).

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes. Notes: I will be overhauling these pages soon-ish, with a less cluttered appearance and more accurate information. This includes the sub-pages. If you have any questions, please go to my discussion page. -Trashboyjet

To do: See if there's any more content from the Booster Packs. Also document the older versions of things pre-booster packs.

Afterbirth+ is the second expansion pack for The Binding of Isaac: Rebirth. It features new content and long awaited built-in mod tools and documentation.

Image file: \gfx\bosses\afterbirthplus\deliriumforms\afterbirth\boss_ultragreed_body_beard.png

In early screenshots of Afterbirth, Ultra Greed had a beard. No files for it were found in Afterbirth. However, in the DeliriumForms folder, the entire spritesheet oddly shows up.

Early Ultra Greed

Image file: \gfx\bosses\afterbirthplus\deliriumforms\afterbirth\boss_ultragreed_body.png

In the same files with Bearded Ultra Greed, an early Ultra Greed between the Beard version and the final. Main differences include a fatter Ultra Greed and incomplete sprites.

Ultra Greedier

Image file: \gfx\bosses\afterbirthplus\boss_ultragreedier.png

While Ultra Greedier is a retexture of Ultra Greed, it would only make sense to have minor leftovers.

Big Horn's Big Bomb

Image file: \gfx\bosses\afterbirthplus\boss_bighorn.png

Big Horn has an unused big bomb. Nothing else is known about it. Bombs of similar size, known as Giga Bombs, would later be utilized in Repentance.

Sideways Lil' Delirium Headless Baby

Image file: \gfx\familiars\delirium\familiar\familiar_shooters_269_headlessbaby

The Lil' Delirium form for Headless Baby has sprites for it facing sideways, like its regular version. These also go unused, as its sprite never changes regardless of the direction the player is facing.

Inactive Forgotten

Image file: \gfx\characters\costumes\character+017_theforgotten

The Forgotten's spritesheet has an unused sprite for it laying on the ground, intended to be used when playing as The Soul. According to the developers, this went unused due to animation required for switching between the sprites being too complex and long for what was supposed to be an instant transition.

Forgotten's Grave

Image file: \gfx\effects\dirtpatch

Sprites for the dirt patch that unlocks the Forgotten when dug up with We Need To Go Deeper!, colored brown to match the color scheme of most other floors. The dirt patch that appears can only appear in Dark Room, which uses a black version of this sprite to match the ground on that floor.

Dollar Icon

Image file: \gfx\ui\main menu\difficultywidget

Stored with the graphics for the difficulty selection is a dollar sign icon, likely meant for Greedier Mode. In the final game, a simple exclamation mark is used for it.

Hidden Signature

Image file: \gfx\items\pick ups\pickup_016_multibombs.png

To the right side and bottom of most the effects is text labeling what each effect is for, and two of the ones at the bottom goes unused with text saying "SAD UNUSED", and "BIG SAD UNUSED" next to it. Lower right corner has a signature that says "LACAP FALTA DAÑO".

Unused Audio

Inhale

The sound of something inhaling.
