August 30th (Reveal)

A "title reveal" for a new expansion was released by Nicalis on Youtube.

The trailer revealed the title of the expansion and its logo - strikingly similar to that of The Binding of Isaac: Antibirth, a fan-made expansion of the game that received critical acclaim from the community but despite popular demand seemed to have little chance of being brought to the official game at the time.

Additionally, it was announced on Twitter that Repentance would be available for play at the PAX West 2018 Convention.

August 31st

The demo version of Repentance playable at PAX confirmed suspicions that the expansion would indeed be a port of Antibirth. Original content from the mod that led to this conclusion as well as brand new content in Repentance that were discovered in the demo included:

September 1st

Edmund McMillen officially discloses details of the Repentance expansion pack on Twitter.

• The Repentance DLC is officially announced to include the Antibirth mod alongside a ton of other new content - Edmund affirms it is "the FINAL (for real this time) DLC for isaac".
• Edmund will be working with the full team of Antibirth developers (Public Entertainment Networked Interactive Software - also known as P.E.N.I.S), Kilburn, LeatherIceCream, and NotYourSagittarius, on the Repentance DLC, which will also be published by Nicalis.
• Repentance, as a substantial addition to the game, will cost money.
• Repentance has no set release date yet - however, remaining Booster Packs are being worked on and expected to release within the next 2 months on console.
• Repentance will feature a new cutscene(s) & lore in the Isaac story.
• Repentance's soundtrack will be fully composed by original Isaac: Rebirth music composer Ridiculon (in name of cohesiveness) and not Antibirth soundtrack composer Mudeth, contrary to expectation of a full port of the mod's content - Mudeth adds that he will finish working on his own soundtrack nevertheless, but that it will have to be modded in instead.

This reveals the attacks of the floating enemy that has Attack Flies surrounding it.

The gameplay also reveals the Antibirth version of HUD, a new rune that can be seen dropping next to Eve at the end of the video, who has a new hair sprite for her Whore of Babylon state, and possibly a new sprite for Clicker.
