What is The Binding of Isaac: Rebirth?
A roguelike shooter about Isaac, a boy who flees into a basement and fights by firing tears. Every dungeon is randomly generated, and hundreds of items stack their effects as you collect them. Their combinations, or synergies, can enlarge tears, make them pierce enemies or transform them into entirely different weapons, creating a different build each run. There is also an enormous range of unlocks. After a decade of play, the Japanese source's Steam review snapshot recorded over 440,000 reviews rated Overwhelmingly Positive. It is a landmark of the roguelike genre. Note, however, that **Japanese is not officially supported**.

「Item combinations make every run feel different」 — Based on the official Steam store and the review snapshot recorded in the source
1. Randomly generated every time; death ends the run
The dungeon layout and items change on every run, and death ends that attempt. Unlocked characters and items remain, so your options expand the more you play.
2. Item synergies are the heart of the game
Each item adds its effects to those you already have, and certain combinations transform your tears completely. Discovering what will combine this time is what has kept people playing for a decade.
3. Very little is explained
Picking up an item displays only a short phrase, not an explanation of its effects. Whether you learn by experimenting or consult outside information is up to you. Picking things up and trying them is enough to enjoy a first playthrough.
4. A huge range of unlocks
Characters, items, endings and many other features unlock through clears and specific conditions. Even the first few dozen hours can feel like only the beginning.
5. Japanese is not officially supported
Japanese is not officially supported. However, the amount of text is small and many item effects can be understood visually, so the language barrier is comparatively low.
This page uses the official Steam store and mechanics described in the source as unchanged since release. Specific numerical values, item stats and balance details are omitted because updates can change them:
