Press release:
Bratislava, Slovakia, September 22, 2026 – Publisher Blue Brain Games today announced that Quern – Undying Thoughts will launch on Nintendo Switch on October 6, 2026, ten years after the atmospheric first-person puzzle adventure first arrived on Steam.

Explore a world built around puzzles

Quern is an island filled with beautiful scenery, forgotten places, unusual machinery, and secrets waiting to be uncovered.

The game’s puzzles grow more demanding as players move deeper into the island. Observation and experimentation are just as important as logic, with each discovery opening up another part of the mystery.

When you arrive on Quern, you barely have time to clear your vision before the portal closes behind you. Your way back is gone, and the island’s secrets are now the only path forward.

Players must study their surroundings, follow the hints left behind by the past, and work out how the island’s strange mechanisms fit together. As the journey continues, new discoveries reveal unfamiliar locations and offer further clues about Quern’s history.
