You are born into a small, careful society of machines that inherited everything people left behind. Then a megastructure appears that should not exist, and everyone has an opinion about it.

Puzzles that keep opening out

Connectors, jammers, drills and inverters, layered until a room becomes a genuine problem. There are far more of them than the first game and none of them repeat.

The talking is the point

Your companions disagree about progress, reason, faith and whether to repeat humanity's mistakes. You take sides, and the story follows where you stand.

Somewhere worth being

The environments are enormous and calm, and the game is happy for you to wander off and look at them for a while.
