About this game

How deep can you go?

Steer a small yellow sub into a lightless ocean trench. Your lamp is your only light, your harpoon your only friend, and every metre deeper is worth more – if you make it home.

ONE THUMB, ENDLESS DARK
Drag to steer. Your lamp points where you swim and your harpoons fire by themselves at whatever it finds. Easy to pick up from the first second, hard to put down.

WARDENS OF THE DEEP
Every zone ends at a gate guarded by a giant leviathan. It sweeps through the trench again and again. Find the glowing weak spots along its body with your light, and bring it down.

KNOW WHEN TO SURFACE
Air runs out, the hull cracks, the creatures get bolder the deeper you go. Catch rising bubbles for air, collect glowing samples and crystals, and decide when to turn back. Surface safely and keep everything, or lose part of your haul.

BUILD YOUR SUB
Cut your submarine open and grow eight rooms: air tanks, hull plating, lamp, engine, harpoon bay, laboratory, repair bay and cargo hold. Each one is a small working machine that grows with every level.

UPGRADE ON THE WAY DOWN
Every few samples, pick one of three upgrades: wider and longer lamps, twin harpoons, sonar pulses, a shock hull, a magnet and more. Every dive builds differently.

GHOST DUELS
Race rival divers as glowing ghosts in the same trench. Pass the depth where they stopped and climb from Bronze to Legend league.

SOMETHING NEW EVERY DAY
Weekday festivals (Airy Monday, Pearl Tuesday, Warden Hunt Wednesday, Crystal Thursday, Bright Friday, Deep Weekend), daily quests, weekly and monthly goals, and daily and weekly rankings that pay pearls.

A WORLD THAT GETS DARKER
Sunlit waters full of kelp and shoals, the twilight where the first lights appear, the midnight zone where everything glows on its own, and the abyss below.

Fathomfall is free to play. It contains optional in-app purchases and ads.
