New: Reimplemented MCM support.

New: Implemented the option to switch mutation effect shaders for Plaguewalkers and Radiation Walkers.

Changed: Reduced frequency of mutation comments.

Changed: Gene starch cost increased to 16 mutant growth.

Updated on February 17th:

Version 4.0.2

Changed: Mutant Growth's drop rate has been slightly reduced.

Changed: There are fewer new loading screens.

FIXED: Resolved an issue where Meat Food was not working with cooked meat.

Fix: Resolved an oversight where Carnivore was not working with DLC foods.

Version 4.0.1

Fix: Resolved an oversight where mutant growth was dropped too frequently.

Version 4.0.0

Supplement: Serum production! Legendary enemies have a chance to drop Mutated Growths, and after obtaining Class Freak, they can be used to create mutations by recovering from a certain number of unique mutations.

NEW: New mutations! Goat legs, gorilla arms, silver tongues and vicious circles.

New: Custom legendary effects related to mutations, Mutants and Purists.

New: Dialogue reactions for mutated players. Actors will comment on how strange or worrying you look when mutated.

New: Automatic support for ghoul transformation, radiation mutation rate adjusted to match human level.

NEW: Customizable eye color options after gaining Adrenal Reaction or Eagle Eyes.

Changed: Every mutation has been rebalanced to better fit Fallout 4 balance.

Changed: Each mutant serum now has a unique colored rim light effect.

Changed: Genetic starch is now obtained through mutant growth rather than at a preset location.

Removed: Removed essence from merchants. Serum can now only be obtained through crafting and cannot be bought or sold.

Removed: Serum is no longer generated in specific locations, such as the Institute's FEV lab. I've never been a big fan of this feature, I feel like the serum is superior, less invasive and more powerful.

NOTE: There are a lot of other changes, but I've been working on this for months and can't think of every one of them.

Updated on March 26, 2025:

Version 3.0.1

FIXED: Resolved an issue where RadAway was unable to cure Next-Gen mutations.

OPTIMIZED: Small code cleanup and optimization.

Version 3.0.0

NOTE: The mod has been completely rewritten and reworked to improve it in many different areas.

You cannot update from v2.0 to v3.0 on an existing archive. If you ignore this warning, support will not be provided.

However, if you never installed v2.0 in the archive, you can install this mid-save.

Added: Gene Starcher, a new unique reusable consumable that turns the Starched Genes perk on and off. This can be found while working on Virgil's mission in the institute's FEV lab.

Added: If you have the mod installed, soft support for the immersive animation framework is automatically provided.

New: Mutant Serum now spawns from merchants selling rare potions.

Changed: Rebalanced all mutations to fit Fallout 4's scaling and vanilla perks, rather than aligning with Fallout 76's 1:1. Mutation changes are listed in the mod's description.

Changes include (but are not limited to):

  • Scaly Skin/Grounded - Rebalanced DR/ER resistance bonus to % damage reduction since extra DR/ER is generally not very beneficial due to armor calculat …

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
