It’s been years since Repentance – the massive and final expansion to The Binding of Isaac: Rebirth – was announced, and today we finally have a bit more information about it.

Creator of the series Edmund McMillen posted to Steam a few hours ago with a post simply subtitled “It’s Coming!” which talks about the birth of his new child, a Steam page for the expansion, and a few smaller details such as the console version of this content.

The Steam page is available right here and it has a 31st December 2020 release date, though we’re not sure if that is the definite date or simply a placeholder as it’s the very last day of the year.

This store page promises players the following:

  • “30+ new items (more than 700 items in total)
  • A full alternate path with brand new chapters and a new final boss and ending
  • 100+ new enemies
  • 25+ new bosses
  • 2 new playable characters
  • 5 new challenges
  • 100+ new achievements
  • 5,000+ new room designs”

For those thinking that this sounds like a lot of content, well you’d be correct. McMillen states that the expansion is more akin to a full blown sequel, likening it to the massive jump the series experienced when it went from the original Flash game to Rebirth.

Released in 2014 Rebirth was a pseudo sequel and remake of the original game which was made in Flash. To talk about Repentance in the same way is very promising for people who are still playing The Binding of Isaac routinely, which a lot of people are.

Going back to the release date McMillen states that the expansion is 90 percent done and more updates about it will be available in blog form come the middle of October. Other members of developer Nicalis will also provide information in the near future about console ports of Repentance.

The Binding of Isaac is one of the most influential games ever released and Repentance feels like both its swansong and comeback at the same time. It will be interesting to see how it compares to more modern games that it directly inspired, such as Enter the Gungeon.
