The Binding of Isaac: Repentance+

This article is incomplete. Please help to improve it, or discuss the issue on the talk page.

Repentance+ is a free DLC expansion to The Binding of Isaac: Repentance that was released on November 19, 2024.

WARNING: Repentance+ online co-op is still in beta state and it is very unstable and currently suffers from the input delay, bad lag compensation, desync that can disconnect all players and mix up host's save data with desynced user and if they crash, save data is permanently destroyed, or if they complete the run without gaining any new marks, it can sometimes replace the old save data when restarting the run. Play it at your own risk. You can always turn off Repentance+ content in Steam DLC manager.

Features[]

General features revealed include:

A fully reworked Co-op mode, with new online multiplayer modes, including Quick Match, Public Match, Friend Match, Death Match and online Daily Run.
A new emote wheel, allowing users to communicate better.
Text chat functionality.
Many new item buffs and re-balancing adjustments.

Changes[]

The Repentance+ DLC brings with it many changes to old content in the previous game.

Some of the most important changes include (but are not limited to):

Tammy's Head: Reduced the duration of the animation when using Tammy’s Head, allowing the player to fire more quickly after use.

Lemon Mishap: Slightly increased the size of the puddle. Also, the puddle will now persist until the player exits the room.

Mega Bean: Creates a catastrophic fart that sweeps the entire room. (Unlisted Change: This mimics the Mama Mega! explosion effect, for the room it's activated in, allowing it to now open the entrance to Boss Rush and ??? (Floor) if activated in the Mom and It Lives rooms after the timer has exceed the cut-off window.)

Milk!: The familiar now follows closely behind the player and blocks shots. After 10 hits, the glass will break and give the player a Tears upgrade for the remainder of the floor.

Delirious - Summoned bosses will now persist through rooms. Only one boss can be active at a time. The charge is now variable, based on the quality of the previously summoned boss.

Lil Delirium - now contributes to the Conjoined transformation.

Jar of Wisps: Reduced to a 6-room charge, allowing the wisps to stack up to the maximum number more quickly.

Abyss: Item quality now impacts the damage of the summoned locust. Locusts now inherit many different effects based on the item destroyed by Abyss.

Flip: Charge has been reduced to 4 rooms for Tainted Lazarus only.

Portable Slot: Removed from the Shop pool. Added as a possible reward from any Slot Machine.

Void: Charge has been reduced from 6 rooms to 4.

Epiphora: The Tears upgrade from firing in a single direction is now a smooth increase, instead of being staggered every few seconds.

God's Flesh: Doubled the chance of shrink tears firing. Shrunken enemies now briefly flash white before growing back to full size. Enemies that explode, fire shots or summon minions on death can no longer hurt Isaac if they're killed while shrunken.

Hushy: While held in place, Hushy now fires radial bursts of shots.

It Hurts: After taking damage, the player's tears will now leave behind small pools of blood creep for the room.

Mars: In addition to being invulnerable when charging, Isaac will gain a 1-second bubble of invulnerability after the charge. Hitting obstacles also causes a knockback effect to clear any threats from the surrounding area.

Evil Charm: The player now gains immunity to spider-web slowdown, flame attacks, fireplaces and poison mushrooms. Isaac can also stand in enemy creep for 1 second before taking damage.

Vasculitis: Friendly radial shots fired after killing an enemy will now appear as blood clots to more easily distinguish them.

Lil Portal: Has been completely reworked. Double-tapping a fire button is now required to launch Lil Portal. After it has consumed enough items and the room is clear, a single portal will spawn and the familiar will now disappear for the remainder of the floor. Entering this portal now takes the player to a room where he can pick up or drop off items. This room persists throughout the rest of the current run.

Linger Bean: The fart cloud is now deployed after 4 seconds of continuous fire instead of 7 seconds. The cloud starts small and potent, and will grow and deal reduced damage over the course of 10 seconds.

Jupiter: Now heals 2 red hearts instead of just ½.

Butter Bean: Recharge time has been reduced from 3 seconds to 2.

The Bean: Can now be re-used after a 4-second cooldown instead of a room charge.

Kidney Bean Can now be re-used after a 4-second cooldown instead of a room charge.

Dead Bird: Will remain active between rooms as long as the player is at ½ heart. (Note: Eve requires 1 full heart.)

Dataminer: Using Dataminer in a room with an item pedestal will now reroll it into a glitched item.

Tick: Can now be removed by picking up A Lighter.

Error: Now shows which trinket it is emulating.

Short Fuse: Now increases bomb damage by 15% alongside its usual effect.

Tonsil: The number of hits required to create a familiar has been reduced from 12-20 to 6-12.

Wish Bone & Bag Lunch: Increased the chances of both trinkets spawning an item from 2% to 5%.

Once it’s been unlocked, the Void portal is now guaranteed after defeating The Lamb, ???, Mega Satan and Mother. (Note: for Mega Satan and Mother it's only if their respective ending has been seen once by any character.)

Undocumented Changes[]

Deathmatch[]

At the end of a successful run, a PvP minigame is played. All of the players are turned into Isaac and are placed in either a 2x2 or 1x1-sized room filled with rocks and metal barriers. They are given 90 seconds to fight each other.

The regular heart system for health is absent here, with the players instead having more gradual healthbars.

Several types of deathmatch exist, including the following:

Random items from the run will be spawned around the room for players to pick up.

Every player is given Knockout Drops. Blue fireplaces are placed in the corner of the room to knock other players into.

Every player is transformed into a Fatty and given Butt Bombs and Wait What?.

Every player is given Ipecac.

Every player is given Belly Jelly. They are placed in a ring of spikes to knock other players into.

Every player is given Soy Milk, Taurus, Spoon Bender, and the Stompy transformation. They are placed in an arena with several thin, rock-obstructed corridors lined with metal blocks.
Players cannot hurt each other but each player is given a Spirit Sword they can use to knockback each other into the spiked rocks that surround the arena.
Every player is blindfolded and given Bomber Boy, 99 bombs and a golden bomb. They are placed in an arena with the same layout as Wrath/ Super Wrath's rooms, but with metal blocks instead of rocks.
Every player is given Mom's Knife. They are placed in an arena with blue fires and Stone Grimaces.
Every player is given Mysterious Liquid, Aquarius, and Lost Cork.
Every player is given The Ludovico Technique with varying tear sizes.

As this update is fairly recent, this list is not complete, so please add more deathmatch variants as they are discovered.

Multiplayer-only changes[]

As co-op was the main focus of the update, many undocumented changes are only applicable to that mode:

Eternal Hearts can revive a ghost player if picked up by them. This can lead to a hard lock in case the ghost picks up an eternal heart in a zone they could not get out of once revived (eg. without flight) and then the other players disconnect.
