Budapest, Hungary - Developer Zadbox Entertainment and indie publisher Blue Brain Games today announced that Dimhaven - The Lost Source will release on PC via Steam in June 2026. Wishlisted by over 60,000 players, this first person mystery adventure invites players to step into the shoes of Emily Ravenstone and uncover the secrets of a forgotten island.

To mark the announcement, the team has released a lost tape from Dimhaven - not a trailer, but a window into the world itself: the atmosphere, the world, the mood that awaits this summer. A free demo is available now on Steam, offering a glimpse into the retro European inspired tourist paradise and the mysterious events that left it abandoned.
