World Corruption Guide: The Post-Game Toggle, Unlock and Corrupted Maps

What World Corruption Is

World corruption is the game’s answer to “what do I do after the credits”: a settings toggle, added in the 1.1.1 hotfix, that applies corruption to all maps once you have beaten the game. The official notes do not enumerate what corruption changes — that capture is pending — but the game’s own patch history proves corrupted worlds were already a thing before the toggle existed: Corrupted Yomori is named as a distinct map with its own boss ingredients, and world bosses had spawn rules of their own.

How You Unlock It

The gate is explicit: beat the game first. The toggle lives in the settings menu and only functions after a completed run through the final battle. Two design facts reinforce that framing:

• The 1.1.0 patch — the day before the toggle shipped — closed the last escape routes from that final battle: “You can no longer extract in the final battle,” and the extraction guide tracks that rule plus the Emergency Extract loot exploit fix that came with it.
• The same 1.1.0 patch fixed “world bosses not spawning in final mission,” meaning the ending sequence’s boss roster was itself being repaired right up to the corruption toggle’s arrival.

So the intended order is: finish the final battle → unlock the toggle → turn corruption on for every map.

Corrupted Yomori: The Variant on Record

Yomori is the clearest window into how corruption variants work, because the notes treat it and its corrupted twin as separate entities that share a boss system:

The boss-ingredients line is the structural one: a mismatch between the two maps’ ingredients implies corrupted maps re-roll the loot table rather than copying the base map’s — corrupted runs pay differently, which is the standard reason post-game corruption modes exist. The base map’s other confirmed details live in the Yomori guide, and the full map roster sits in the planets guide.

What Corruption Changes — and What Is Still Pending

What the notes prove: corrupted maps exist as distinct variants with their own boss ingredients, and the toggle applies corruption across all of them after the credits. What no public source has verified yet: the actual corruption modifiers — enemy changes, map alterations, drop differences, whether difficulty scales. The 1.1 update overview tracks the toggle alongside the rest of the 1.1 line’s changes; this page collects the corruption-specific evidence as captures land.
