Fans of the hit indie game Binding of Isaac will be excited to hear that another massive expansion is making its way to the title. The upcoming update adds the very popular Anti-Birth mod into the core game and is named The Binding of Isaac: Repentance.

The big announcement was officially made by Binding of Isaac's developer, Nicalis, and was also shared out by the game's creator Edmund McMillen only a couple of days ago. Following the teaser, McMillen clarified a few more details about the expansion (in his own charming way of course).

Fans were initially confused on what Nicalis could be teasing, considering they already have another title on the way, The Legend of Bum-Bo, that is set to look deeper into the Binding of Isaac's lore. Although, The Binding of Isaac: Repentance turned out to be a surprise expansion for a game that fans thought was already complete.

Repentance is expected to add a ton of new content into the already jam-packed game. This includes new enemies, items, bosses, and an insane amount of new rooms for fans to fight their way through. On top of all that, a brand new secret ending that will certainly be the toughest challenge the game has ever seen was also included.
