Colony life. A world of our own.
Nest Rivals
Live the colony.
Shape its world.
Lead from within. Take control of a slime and build a future for your colony.

01 / Nest Rivals
You don't just lead a colony.
You're part of it.
Nest Rivals combines colony simulation with direct control. Take charge of an individual slime while the rest of your colony lives and works around you. Gather food, explore the world and help a small nest grow into a living colony.

02 / Nest Rivals
A journey through
changing worlds.
Guide your colony through a campaign of different worlds and challenges. New environments, rival species and changing conditions ask you to adapt without telling you everything in advance.
Each stage explores a different situation within the simulation — from establishing a first colony to surviving unfamiliar environments and competing with other species.

03 / Nest Rivals
One nest
becomes a colony.
Gather nectar, establish new nests and spread through the world. What begins with a queen and a handful of slimes can grow into a colony spanning the surface and underground.

04 / Nest Rivals
Small creatures.
Big discoveries.
Explore procedural worlds filled with different habitats, creatures and resources. Much of the world begins unknown — what lies beyond your colony has to be discovered.

05 / Nest Rivals
Same world.
Different rules.
Water, heat, darkness and hostile terrain don't affect every species equally. What protects one colony can threaten another.
Learn where your colony thrives — and where its rivals don't.

07 / Nest Rivals
Life above.
A home below.
The surface is only half of the colony. Travel underground, move through chambers and entrances, and expand the nests that keep your colony alive.
Field notes / Nest Rivals
A world worth
looking closer at.
Creatures, species and places enter the illustrated Bestiary as you discover them. Its pages preserve what you've learned across different worlds and gradually reveal more about the ecology and history of Nest Rivals.
