Lead the Last Survivors. Rebuild Hope!
The continents have sunk. Cities and mountains lie beneath the waves. All that remains is a boundless ocean—and a single floating lighthouse sanctuary.
As leader of the last refuge, you must build, survive, and lead humanity’s revival in a world consumed by water.

BUILD YOUR FLOATING STRONGHOLD
Expand from a crumbling lighthouse into a sprawling sea base.
Gather driftwood, salvage steel, and construct wave-resistant platforms.
Assign survivors as engineers, divers, medics, and sailors to keep your bastion afloat.

SURVIVE UNFORGIVING STORMS
Brace for hurricanes, acid rain, and rogue waves in a dynamic weather system.
Reinforce shelters and stockpile resources before disaster strikes.

EXPLORE THE DROWNED WORLD
Dive into sunken cities to recover lost tech and rare materials.
Discover drifting ruins, hidden outposts, and pirate fortresses with unique risks and rewards.

DEFEND AGAINST SEA THREATS
Fend off sea raiders with turrets, explosive nets, and elite boarding squads.
Face legendary sea monsters rising from the deep—repel them or tame their power.

FORGE ALLIANCES ABOVE THE ABYSS
Trade with other ocean settlements—but beware of betrayal.
Join global sea events: escort convoys, rescue missions, and titanic boss battles.
