Mutators

R.E.P.O. Mutators

Inject some chaos (and possibly despair) into your R.E.P.O. runs with Mutators! Random level modifiers will be chosen to alter your current level in some way.\ NOTE: Everyone needs this mod for it to work. Singleplayer currently experimental.

Major update V1.0.0: Multi-mutators

Multi-mutators are now available! Multi-mutators allow the possibility of multiple mutators being active at the same time.

The scaling type can be adjusted in the mod's config:

Scaling Type — Description

| Moon | Default configuration. The amount of active mutators scales with the game's moon phases. | Random | The amount of active mutators is randomly chosen between a configurable minimum and maximum. | None | The maximum amount of active mutators is always 1. This is the old behavior.

Additionally, a rules file is now provided to allow for more fine-grained control over mutator selection.\ Don't like a particular combination? Just set a mutual exclusion rule in the rules file.

Really like a particular combination? Consider creating a custom multi-mutator!
