Deepdig Colony

A small colony. A lot of rock. Not enough air.

Deepdig Colony is a procedurally generated colony sim in the spirit of Oxygen Not Included. Dig out rooms, build ladders and tiles, place cots and mealwood, and keep an eye on the gas overlay. Your orders shape the colony while its colonists get on with the work.

Play directly in your browser. On a phone, drag to place orders, use two fingers to pan and pinch to zoom, or use the Pan and zoom buttons. Pause whenever you need time to plan. Both portrait and landscape are supported.
