Game help

The How to Play guide covers controls, banking, and your first upgrade. Look up a weapon in Equipment or a creature in the Bestiary. Recent changes are listed in Updates.

You do not need an account or download to play. On a phone, play in landscape. Your current ship belongs to the live session. Sign in to enable quests, achievements, Scrap, and cosmetics and save progress across devices. Guests can still access combat, depth trials, merchants, and exploration. Settings stay on the device. The service is for ages 13 and older.
