Astra cleared RimWorld from one sentence

The instruction was one sentence: decide everything yourself, and clear the game. Apocriton did not hand GPT-6 Astra a build order, a research path, or a reminder to feed anyone. RimWorld punishes exactly that kind of absence. Raids arrive. People get hungry. A bad call compounds.

Astra searched the web, drove the computer, and wrote files it could read back later. The colony survived the raids. Everyone left the planet, including the chinchilla they started with. That last detail is what makes the claim feel played, rather than summarized.

An agent demo often ends on a successful tool call. This one ends on an ending the game itself recognizes.
