Equip yourself with a variety of gadgets to light your way, locate mission objects, and overcome the challenges of the deep.

Use immersive voice chat to coordinate with your team, but beware—the horrors of the deep will test your nerves and your ability to keep it together.

Thalassophobia demo
Hey everyone! First off, thank you so much for playing the demo and sharing your thoughts.We’ve been going through all your comments and feedback here on the community page. We can see that the demo is still a bit rough around the edges. Alot of bugs, some confusion about what to do, and a few things that just don’t feel clear enough yet. That’s totally fair, and we appreciate you pointing them out.We’ve logged the bugs mentioned in the discussions, but if you have any gameplay clips or videos of your reactions while playing, please share them with us! Seeing how players actually experience the demo helps us understand what needs work (after years of development, it’s easy to get a bit blind to it).We’re also inviting you to join our Discord (https://discord.com/invite/uMt2tBcaZc). That’s where we’ll be running upcoming alpha tests, sharing new builds, and letting players try out new levels and features early.Thanks again for all the support. We’re hard at work polishing the game, and will only launch the full game once it feels polished enough for us!Read full article on Community Announcements (Kettunen)
