The Binding of Isaac Afterbirth Plus

The Binding of Isaac: Afterbirth Plus is the definitive expansion to the acclaimed roguelike action game The Binding of Isaac: Rebirth. Released in 2017, this add-on pushes the original formula to its limits with a massive injection of content: over 55 new items, a brand-new final chapter complete with its own boss and ending, a fresh playable character, and a Greed hard mode that adds a punishing twist to the already brutal gameplay loop. If you have already exhausted Rebirth and its first expansion, Afterbirth Plus gives you a reason to dive back into the basement.

This page covers everything you need to know about the expansion — what it adds, how it plays, and where to grab it. You can also explore the base game through our The Binding of Isaac Rebirth Free Download page if you are new to the series, or jump ahead to the latest chapter with The Binding of Isaac Repentance Free Download.

What Afterbirth Plus Adds to the Basement

Afterbirth Plus is not a standalone game — it builds directly on The Binding of Isaac: Rebirth and its Afterbirth expansion. The headline addition is a new final chapter that concludes the story with a unique boss encounter and ending. That alone changes the pacing of a full run, because you now have a definitive endpoint to chase beyond the existing floors.

The expansion also introduces a new playable character, which brings a different starting stat line and item synergy to every run. Greed hard mode and daily greed runs extend the wave-based Greed mode with tougher enemy layouts and a competitive daily format. Five new challenges, a batch of new bosses, and dozens of new achievements round out the package. For players who enjoy tinkering, the included developer tools are arguably the most impactful feature: they let you design, edit, and play an endless number of mods, features, and even whole new games that the community can share.

Key Features

• 55+ new items that expand item pools and open up fresh synergies with existing pickups.
• New final chapter with its own boss and ending, giving full runs a definitive conclusion.
• New playable character with a distinct starting loadout and playstyle.
• Greed hard mode and daily greed runs for wave-based challenge seekers.
• 5 new challenges that test specific item combinations and movement skills.
• Loads of new achievements to chase across both normal and Greed modes.
• New bosses that add variety to the enemy roster and require new strategies.
• Developer tools for designing, editing, and playing mods — including community-made content and total conversions.

How It Plays

The core loop remains the same: you guide Isaac (or one of the unlockable characters) through a series of randomly generated basement floors, clearing rooms of enemies, collecting items, and fighting bosses. Death sends you back to the start, but unlocks and achievements persist. Afterbirth Plus tightens that loop by adding more decision points — every new item in the pool changes what you might find, and the new final chapter gives skilled players a clear target.

Greed mode, introduced in the previous expansion, gets a hard variant here. Instead of a standard floor layout, you survive waves of enemies in a single arena and spend coins between waves. Daily greed runs add a leaderboard-style challenge where everyone gets the same seed. If you enjoy optimizing builds and adapting to random drops, this mode alone can eat hours.

The mod tools deserve special mention. They are not a token addition — they let you create custom items, rooms, and even entirely new game modes. The community has used them to produce everything from quality-of-life tweaks to full overhauls. If you have any interest in game design, this is a rare opportunity to learn on a proven engine.

Pros & Cons

• Pros:
  • Massive content bump — 55+ items, new bosses, and a new chapter extend the life of Rebirth significantly.
  • Mod tools open the door to community creativity and long-term replayability.
  • Greed hard mode and daily runs add structured challenge for veteran players.
  • New playable character changes up run dynamics from the start.
• Cons:
  • Requires the base game (Rebirth) and the Afterbirth expansion — it is not standalone.
  • The difficulty curve is steep; new players may find the new chapter and Greed hard mode punishing.
  • Mod tools assume some familiarity with game logic and may overwhelm casual players.
  • Some content overlaps with later expansions, so players moving to Repentance may not need everything here.

Who Should Get Afterbirth Plus

This expansion is aimed at players who already own Rebirth and Afterbirth and want more of everything: more items, more bosses, more challenges, and a proper ending. It also suits creative players who want to build mods. If you are completely new to the series, start with the base game first — our The Binding of Isaac Afterbirth Plus page assumes you have the core game installed. For those ready to move on, Repentance is the next step.

Trust Signals and Installation Guidance

Version freshness: This is the 2017 expansion release. Because the input does not specify a build number, treat the version as an estimate. The expansion has not received new official content since release, so the version you download should match the final 2017 build.

Publisher details: The input does not provide a developer or publisher field, so we have not invented one. The game is widely associated with Edmund McMillen and Nicalis, but confirm details on the official store page if you need certainty.

Installation guidance: Afterbirth Plus is an expansion, not a standalone executable. You will need The Binding of Isaac: Rebirth and the Afterbirth expansion installed first. Download the files from the links provided in the download section, extract them if they are archived, and place the expansion content in the correct game directory. If you are unsure, follow the guide linked in the download section. We do not claim malware scanning or “100% clean” status because that evidence is not provided here — always scan downloaded files with your own security software.
