// The problem
Survival games mostly gate progress behind fights. This one asks what rebuilding would really take: every obstacle is an engineering problem — cold, water, bad air — and a player who never fires a weapon can still reach everything.
// What was built
- Smooth voxel terrain that can be dug and built on anywhere.
- Building from real parts: sills, joists and boards cut to size, carried and fixed in place.
- Fire and heat, tools, and power and water networks.
- The opening: waking in the sealed bunker, the register of the ten, and the hatch.
- A bunker and ten people made to look like a film rather than a game.
// Engineering
- Godot 4 and GDScript, about 39,500 lines.
- The game is a client of its own local server, so playing alone and playing online run the same code.
- Terrain meshed on worker threads, four times faster than on one.
- 2,858 headless checks in 42 suites, and scripted playtests that play the game through its real input.

A real bunker, real land and a film grade; the people rebuilt as MetaHumans.
// What comes next
- The first ten: the nine companions, hunting and fishing, and studying scrap.
- Then online: persistent servers that run for years, a world that grows by update, and people who age and hand on to heirs.
