SEADRAGON
A riveted 1950s submarine cuts a cone of cyan searchlight through black water, past spiked sea mines chained to the floor, while a violet glow pulses from a trench far below.

Pacific Theater · 1953 · Depth

The carrier didn't sink.
Something pulled it down.

You command an experimental submarine with one searchlight, four torpedoes in the rack and air for twenty minutes if nobody panics. Below you: a minefield, a missing carrier and a light that shouldn't be there.

A new game inspired by the 1980s classic. New code, new art, new story.

A broken 1950s aircraft carrier half buried in silt on the sea floor, lit by a single searchlight beam, with old propeller planes on its tilted deck and a violet light deep inside an open hangar.

What the full game holds

Sea Dragon is a 2D side-scroller built to look and light like 3D. Your searchlight is your sight line; everything past it is guesswork and sonar. Missions run from coastal minefields to the deep trench, and the ocean gets stranger the farther down you go.

An enormous ribbed alien structure with glowing violet seams rises from an abyssal trench, ringed by chained mines, while a tiny submarine approaches.

Final dive · classified

At the bottom of the trench, something has been .

Every chain in the minefield leads down. Every missing ship in the Pacific left a trail. The last mission asks a simple question with a bad answer: who laid the mines, and what are they guarding?
