The Binding of Isaac: Repentance+ Update Guide

Repentance+ is a major free update to The Binding of Isaac: Repentance that added online co-op multiplayer, extensive item rebalances, new items and trinkets, character adjustments, and quality-of-life improvements. It represents the most significant post-launch patch since Repentance itself, affecting meta strategies, Dead God routes, and how players approach daily runs and co-op sessions.

Online Co-op Multiplayer

The headline feature is online co-op for up to four players. Host a run from the character select screen and invite friends through Steam, console networks, or platform friends lists. Each player controls an independent character with separate items, health, and active slots. Shared resources include coins, keys, and bombs. Devil and angel deal choices affect all players. Co-op runs respect the host's unlock state — guests can use characters the host has unlocked even if they haven't unlocked them personally. Dead players become ghosts with weak attacks until revived.

Major Balance Changes

New and Changed Items

Repentance+ added new items, trinkets, and cards while rebalancing existing ones. Items that were quality 3 may have shifted to quality 2 or vice versa, changing Tainted Lost's shop filtering and Sacred Orb reroll outcomes. Community tier lists shifted significantly after the update — consult our quality tier list for current ratings. New co-op-specific interactions allow certain familiars and orbitals to benefit all players in range.

Impact on Dead God Progression

Dead God requirements remain the same in Repentance+ — all hard mode marks, all items, all secrets, all challenges. Co-op can help with difficult character marks by having skilled friends assist, but completion marks only count for the host character. Pool dilution from new items means fresh saves should still follow optimal unlock order. Repentance+ daily runs use updated generation rules and appear on separate leaderboards from pre-update dailies.

• Co-op marks — Only the host earns completion marks. Guests gain no progression credit.
• New secrets — Repentance+ may add new secrets; check our secrets list for the full catalog.
• Mod compatibility — Popular mods like External Item Descriptions updated for Repentance+. Verify mod versions before playing.
• Save migration — Existing saves carry forward. No reset required, but new items enter pools immediately.

Whether you are returning after a break or pushing for Dead God, Repentance+ refreshes the Isaac meta without invalidating your existing progress. Use co-op to knock out difficult Tainted character marks, revisit our Dead God guide for updated strategies, and check individual character pages for Repentance+ specific stat changes.
