The store description explicitly describes it as "a polished, one-sitting game" and "a self-contained short story" — language the developer consistently uses for games in this series that launch as complete, finished products with no post-launch content cycle. There are no DLC listings, no announced expansions, and no developer news posts indicating any planned additions. The game has been available for purchase since May 2018 with no updates suggesting ongoing content development. This game launched complete and has remained so.

About this game

JOIN THE DISCUSSION, DIAGNOSE HUMANITY

Amid a global pandemic, an unknown entity has come to Earth. A small group of humans now face a decision on behalf of their planet: Should they trust the stranger that arrived from the stars?

Quarantine Circular places the fate of a vulnerable human race in your hands. Your dialogue choices in conversation with your fellow humans and off-world visitor will determine how the game plays out, and how its story ends. Work with your team to figure out if your new alien acquaintance is here to help the human race, or whether they plan to strike while the planet is weakened. 

This self-contained short story takes around two hours to complete and is split into several chapters. You can play the game in one sitting or, if you prefer, unfold the story in smaller pieces that can fit into a busier schedule.

Quarantine Circular is inspired by classic adventure games and modern dialogue systems, and developed by the award-winning team behind Thomas Was Alone, Volume, and Subsurface Circular. You do not need to have played Subsurface Circular in order to follow Quarantine Circular’s story (though if you enjoyed one, we think you’ll like the other).

Key Features

  • A polished, one-sitting game.

  • Social dynamics and greater choice enhance this twist on classic text-based adventures.

  • Responsive soundtrack by Dan Le Sac.

  • Unlockable ‘Mr Commentary’, our interactive take on a developer’s commentary.

FAQs

If this game is ‘short’, what’s to stop me getting a refund when I’m done?

We’re so grateful to the community for the low rate of refunds on our previous short, Subsurface Circular. We hope Quarantine will earn the same. Our games are made by a team of hardworking people, and it’s encouraging that the Steam community consistently shows respect for this passion and effort.

Do I need to have played Subsurface Circular or other Bithell games to enjoy this one?

No. Quarantine Circular tells its own self contained story.
