Alpha Early access build
Download Underbriar
A small rabbit. A vast, darkening wood.
Rebuild a fallen woodland society, alone or with friends: forage and craft, grow up and grow strong, and bring the lights back to villages the wild forgot.
A friend is waiting
There’s company in the woods.
Open Underbriar to add your friend’s world and join.

A vast, procedural wood
There are still lights in the wood.
Every world grows from its own seed: six kinds of forest, rivers and ponds, ruins and broken roads, night falling over all of it. Walk far enough and you find what is left of other towns, and what lives between them.
Co-op
The woods are better with company.
Host a private world and send your friends an invite. Forage, build and fight side by side; rabbits survive by numbers, never by strength.
- Start your world. Multiplayer → Host your world, then enable hosting.
- Send an invite. Copy the invite link and share it with your friends.
- Step into the same woods. They open the link, choose Open Underbriar and join. The host keeps the game running.
Settlements
Rebuild what was lost.
You find refuge in a failing village in a bad place. Mend its homes, relight its hearth, raise walls and a hall. Fed and safe, its people settle in, work their trades and build beside you, until one day it is yours to govern.
Roads, mounts and carts
Lay the road home.
Buy a deer and ride it. Hitch a cart and haul timber back to town. Govern a town and build roads to the others, from a trodden path to lamplit stone, and watch the carters take to them.
Skills, crafting and cooking
Grow by doing.
Twelve skills rise as you use them. Forage, farm and cook; craft from bushcraft to copper and iron, in poor, good and fine. Grow up from a kit with a single heart into a grown rabbit who can face a wolf head on.
Quests, sieges and the map
Stories the woods tell.
There is no main story written for you. A letter on a body, tracks by a loner’s hut, a town under siege: quests grow out of the world as it is, and what you do there is remembered.
Below the roots
Follow the light down.
Old passages run beneath the wood. Take a light, find your way, and listen to what moves in the dark.
The fallen kingdoms
Find what the forest keeps.
Broken roads lead to more than villages. Beyond the trees, old walls still stand, and passages lead beneath the ruins. There are mysteries left in the wood.
Predators and legends
The woods have teeth.
Foxes, wolves, wolverines and bears are stronger than you, and they hunt in packs. At first you flee and hide. Gear, skill and friends slowly turn the odds, and far from home, rare legends wait.
Relations and friendship
Make a life in the wood.
Fish by the river and find a place in a woodland village. Every villager has a trade, a home, friends and a wish of their own. Win them over one by one: a true friend will follow you into the dark. Families form and children grow up. No one is safe forever.
Grim, but fair.
The world has largely fallen to wilderness, and nobody quite knows why. There are no cities: only a few sad villages and the ruins of others. The rabbit is small and the night is long. Everything good in this world will be your work.
Download the alphaBefore you set out
Installing the alpha
Mac: unzip, drag Underbriar to Applications, then open it. This early build is not notarized. If macOS blocks it, use System Settings → Privacy & Security → Open Anyway after trying to open it.
Windows: extract the entire ZIP to a permanent folder and run Underbriar.exe. It is an unsigned early build. If Windows asks, review the warning before choosing to run it.
Linux: extract the archive and run Underbriar.x86_64. If your desktop asks, allow the file to run as a program. A recent 64-bit desktop with an OpenGL 3.3 capable driver is needed.
Launch once from the place you’ll keep the game. Windows and Linux then register Underbriar invite links for your user.
Mac: unzip, drag Underbriar to Applications, then open it from there. Underbriar updates itself only from Applications: opened where it was unzipped, it asks to be moved.
Windows: run the Setup. It installs Underbriar for your user, with no admin rights, and starts it. It is an unsigned early build: if Windows says it protected your PC, choose More info, then Run anyway.
Linux: allow the AppImage to run as a program (its properties, or chmod +x), keep it where you’ll keep the game and run it. It updates itself in place. A 64-bit desktop with Vulkan drivers and glibc 2.28 or newer (Debian 10, Ubuntu 20.04 and later) is needed.
Underbriar checks for updates at its title: when one is ready, Restart to update. A friend whose game is older is asked to update before joining, with an Update button.
The invite didn’t open the game
Your browser may ask permission to open Underbriar. If nothing happens, launch the installed game once and try again. You can always use Copy invite, then paste it into Multiplayer → Add server.
Invites give access to a private world: share them with the friends you want to play with. The host can reset access from Multiplayer → Host your world → Advanced.

What does alpha mean?
Underbriar is playable but far from finished. New systems arrive often and some are rough; art, balance and saves can change from one update to the next, so a world may need to start over. Friends playing together should all use the same build.
