Bethesda appears to have shadow-dropped (intentionally or not) a new mobile game set in a familiar universe. The Elder Scrolls: Castles is a building management game reminiscent of Fallout Shelter. The title, first spotted by Reddit user u/tracteurman (via GamesRadar), is available for Android but not iOS.

The Elder Scrolls: Castles tasks you with controlling a castle — and your dynasty. “Oversee your subjects as the years come and go, families grow, and new rulers take the throne,” the game’s Play Store description reads. It describes a real-life day in the game covering a year within the virtual world.

Its gameplay involves familiar staples of building management sims: customize the castle, add and expand rooms, decorate, place monuments and assign workers to stations. In addition, you can create heroes to embark on “epic quests” to battle against classic Elder Scrolls foes.

The Play Store listing’s “What’s new” section says, “Welcome to early access,” which at least suggests the game may have been intended as a closed beta. However, it’s downloadable and playable to anyone with a Play Store account at the time of publication. We reached out to Bethesda to find out whether the game’s silent publication was intentional, and we’ll update this article if we find out more.

The Elder Scrolls: Castles is free in the Google Play Store. It’s rated “Teen” for violence and suggestive themes.
