Repentance expands Isaac again with new items, playable characters (including one that’s actually two character), floors, enemies, bosses, room layouts, achievements, and challenges, an art style tweaked to be a bit closer to Flash Isaac, and a new final boss with a new ending. And presumably some secrets. It’s made with some of the folks behind the huge mod Antibirth, and many of its additions are based on that, though loads is new too. It also adds proper co-op, with selectable characters instead of those lousy babies. Cooperative multiplayer is still officially local-only but it does support Steam Remote Play for online. The update notes showing changes between Afterbirth+ and Repentance are huge. So many items, rooms, enemies, and systems have been tweaked, rebalanced, and reworked. And I’m stoked for the new synergy system, which allows for so many more items to have interesting effects when combined. It will take me so long to learn and internalise all these changes, not to mention everything new in the expansion. Though I’ve played 1300 hours of Rebirth and seen, unlocked, and beaten everything, now I’m a clueless fool all over again. Alright, let’s go. The Binding Of Isaac: Repentance is out now for Windows on Steam at £11.39/€12.49/$14.99. No Mac release this time. You do need all previous expansions too, though they and the base game are half-price right now. It’s also on the Epic Games Store too now, with no discounts. A sequel is an eventual possibility, mind. McMillen said in an interview last week, “Isaac 2 will happen one day, but it’s not going to happen any time soon.” He has years of work planned before he’d start any such thing, including finishing cat-breeding game Mewgenic.
