Co-op voxel survival in a world of ash and ember. Gear up with your crew and climb The Spire.
Free browser alpha. Invite-link worlds, soft-adventure pace, real boss at the top.
Checking worldWhat you are in for
Small crew. Open world. One tower that matters.
Co-op survival
Drop into one shared world with your crew. Mine, build, and hold the night together — everything syncs live in the browser.
Gear ladder
Start with a stick and a plan. Smelt ore into better swords and shields, and earn skill points that push your build further.
The Spire
A tower looms over the ashlands. Gear up, climb floor by floor, and face the Keep Lord waiting at the top.
Private worlds
Worlds are invite-link only. Share a code with friends, or lock it with a password so only your crew gets in.
How it works
In a world in under a minute.
Grab an invite
Create an invite code for your world, or paste the one a friend sent you.
Play in the browser
No install, no launcher. The client loads straight into the world on any desktop browser.
Survive and climb
Gather, forge, fight. When your crew is ready, take on The Spire.
