01 / The experience
Less noise.
More unknown.
A quiet adventure with a pulse of tension. No crowded maps. No race to the finish. Just you, your instruments, and an ocean that opens up one discovery at a time.
02 — DISCOVER
Meet the extraordinary.
Find bioluminescent life, forgotten research equipment, and curious signals. Build a field journal of the world beneath the waves.
03 — EVOLVE
Earn your next descent.
Return with discoveries. Reinforce your hull, sharpen your sensors, and trade a familiar route for a deeper, stranger expedition.

02 / The descent
The deeper you go,
the less you know.
The last of the light.
Learn your vessel as the blue fades. Drifting silhouettes mark the beginning of another world.
A language of little lights.
Follow living constellations through open darkness. Listen closely: not every signal is a creature.
Beyond the ordinary.
The walls close in. The pressure rises. Piece together the final logs of an expedition that came before you.
03 / An instrument for the unknown
Darkness isn't empty.
Send a signal.
Your eyes only take you so far. A sonar pulse reveals the shapes beyond your lights—and sometimes a reason to change course.

Before you dive
A quick briefing.
Can I download HADAL now?
Not yet. HADAL is a game concept in development, with iOS and Android as the intended platforms. This page offers a small sonar demonstration, not a downloadable build. Join the update list for future release news.
Is this a survival horror game?
The direction is atmospheric exploration, not jump-scare horror. Expect isolation, deep-water tension, and resource decisions balanced with the wonder of discovery.
Is the trench scientifically accurate?
The setting draws inspiration from real ocean depth zones and the Mariana Trench. The terrain, expedition story, and encounters are creatively interpreted for play; HADAL is not a diving simulator or navigation tool.
Will it be free to play?
Pricing, device requirements, and offline availability have not been announced. Those details will be shared as development progresses.
