The rogue-like strategy game Offcoast plays out in a subterranean, underwater landscape.

Travel with ship and crew into the deep oceans in search of a rare blue-green algae.
Collect scraps. Upgrade the ship. Improve the crew.

Note: The basics of the game is very close to that from FTL: Faster than Light, but moved down into an underwater environment instead.
This together with several new game systems added to the game should however offer a new experience - whether or not you have already played FTL.

The world has entered a time where life is only sustainable along the coast or on water.
Corporations are the new government - and rule the world from their iron cities.
Raider-factions have arisen and fight for the bitter fun of violence - and the freedom-resistance faction does what it can to restore the world.

Find and store the precious algae for the sake of the earth.
All algae found is stored on your account and will unlock more ship-types, more factions and new difficulties.
It will also allow you to specialize into new different class-types of crew.

Explore the waters, dive deep - and excavate old relics from previous mutant civilizations.
