01 / THE FIELD

The sea is alive.
The platforms are empty.

You wake in the dive team’s lifeboat after six days of decompression. An abandoned field stands above the North Atlantic. The lights are out. Every crew member is gone.

Splice the burned cable. Throw the breaker. Then cross the bridges and bring the field back, one platform at a time.

02 / LIFE OFFSHORE

Find a rhythm.
Stay through the night.

Fish, salvage, cook, and build a place to come back to. Watch the weather. Keep a light burning.

ABOVE THE SURFACE

Make the field your home.

Cast from the rails. Collect rain, grow food, and turn salvaged materials into shelter. When the crabs climb onto dark decks, the light is yours to build.

BELOW THE SURFACE

There’s more beneath you.

Follow the platform legs into kelp and reef. Dive for supplies, fish the deeper water, and watch for the hammerheads moving between the rigs.
