Fly a small mining pod down through the rock. Fill the hold with ore, get back up before the fuel runs out, sell it, and buy a bigger drill. Build a base on the surface and hold it when the critters come at night. Luna, Mars, Io and Callisto, with a guardian machine asleep under each.

What a Steam playtest is

A playtest is a test build of a game that developers offer before release. On Steam you sign up for testing on the game's page. Whether you get access immediately, or the developer invites you first, is decided by the developer and can change.
