Colony simulation · In development

Subterrans

A spiritual successor to SimAnt. Tune their priorities, dig your nest, out-think the rival colony below. Above ground is just the surface.

Phase 3 is shipped: real combat math, an AI that invades on its own schedule, and a neutral predator. A round now has a beginning, middle, and end.

The enemy colony gets a new brain

The complaint I hear most — the AI is too easy, it always dies — finally gets a real answer: two sim fixes that give the enemy teeth. And the enemy colony can now be driven by Jev, TypeSafe's decision model, on standing orders you write yourself. Playtest coming soon.

What people are saying

Early playtester puns

The game

Seven essential systems. A colony you can lose. A world that rewards patience.

The experiment

Built with AI coding agents as a real part of the toolchain, not a gimmick.

The roadmap

Where things are, with phase names and statuses. No dates.
