Koop The Piper of Dawn PC

Become an alchemist in Diamond City, where growing a business means growing your own workers. Farm, craft, and sell your creations as you build relationships and navigate a dark fantasy story with multiple endings.

• Build Your Alchemy Business: Grow magical crops, craft valuable goods, and put your homegrown workforce to work.

• Meet the City's Unusual Residents: Discover over 40 NPCs and relationship paths for six central heroines.

• Shape the City's Fate: Earn the trust of six factions and explore branching stories shaped by your choices and reputation.

Grow ingredients, turn them into valuable creations, and sell them to fund your next expansion. Along the way, fulfill orders, build relationships, and uncover the city's stranger side.

Cultivate the Extraordinary

Grow over 100 crops and experiment with traits to improve your harvests. Expand underground and use alchemical circles to build a flourishing, self-sustaining farm.

Turn Curiosities into Profit

Decorate your shop and stock its shelves with crops, potions, and rare curiosities. Build your reputation to attract non-human customers and unlock lucrative special orders.

Grow Your Own Workforce

Meet the Peoplesprouts: workers you grow yourself. Assign them to farming, retail, and manufacturing to automate your business.

Match their talents to the job—and give them time to recover. Overwork takes a toll on their Sanity.

Turn Experiments into Opportunity

Transform materials into valuable goods or grant your Peoplesprouts powerful abilities. Experiment with volatile elements and combine alchemy with Oracles to discover extraordinary results.

Borrow the Power of Ancient Gods

Collect and combine divine blessings for powerful bonuses during each time rewind. Just beware of the gods behind them—and the influence of their whispers.

Decide Who to Trust

Win the favor of six rival factions to unlock special orders and new story possibilities. Your reputation and choices help determine how Diamond City's story ends.

Oracle Summons

Try your luck summoning blessings from Ancient and Outer Gods. Their gifts could be just what your next experiment needs.

The Golden Cage Card Parlor

Challenge the city's residents to Blackjack. When luck fails, remember your two favorite gods: Save and Load.

Fishing

Cast your line across Diamond City and reel in fish, strange surprises—even an Ancient God.

Sissi

A barmaid blessed with superhuman strength—and your very first full-time hire. She originally dreamed of becoming a housemaid, only to discover a surprising natural talent for farming.

Nene

The daughter of a mathematician, Nene has a brilliant mind, razor-sharp intuition, and the combat skills to back them up. But her true talent shines through in the end: after becoming a Peoplesprout keeper, Nene finally found the perfect place to put her skills to use.

Gretel

Feel like adventuring alone is far too safe? Then bring this amazing trouble magnet along! She'll bring a never-ending stream of danger your way.

With shimmering rose-gold fur, a fluffy tail, and incredible marksmanship, Gretel seems to encounter mysterious incidents wherever she goes, recording each one in her Field Notes.

Jimo Li

Meow? Meow, meow!

Aurora Ludwig

Princess, goddess, sacrifice... Aurora bears many identities and possesses extraordinary magical power that greatly influences Diamond City itself.

A woman shrouded in mystery, her true nature remains impossible to discern.
