Read the land.
Find fibres, timber and stone. Follow the local geology, dig into soil and mine the rock beneath it.
A world worth beginning again.
Wake in a forgotten bunker. Carry knowledge into the wild. Turn stone, soil and fire into the beginnings of a new life.
Explore the free pre-alpha01 / After the silence
You open your eyes beneath the surface. An archive of practical knowledge survives beside you. Above, the landscape stretches beyond the bunker: unfamiliar, indifferent, full of possibility.
Diod is about learning to live here. Weave your first bag. Shape a tool. Build a fire. Every small discovery makes the next one possible.
Find fibres, timber and stone. Follow the local geology, dig into soil and mine the rock beneath it.
Craft what you need, build a camp and grow your first food. Tame a horse to travel farther and carry more.
Work from stone tools toward iron. Forge the pry bar that opens the bunker’s sealed cryo wing.

02 / Built on Earth
The terrain takes its starting point from real Earth data, generating playable chunks as you travel. Your excavations, camp and supplies persist when you return.
The current build focuses on the first chapter: surviving alone, learning to craft, and reaching the first survivor. The wider settlement journey is still being built.
03 / Join the beginning
Diod is free during pre-alpha.
Expect rough edges, evolving visuals and unfinished systems. Play, explore, and help shape what comes next.
