One Breath: Deep Dive

An endless dive on a single breath. Swim past where the light gives out, dodge whatever lives down there, and spend what you bring back on gear that gets you deeper.

How deep can you go on a single breath?

One Breath is an endless underwater diver. Touch anywhere and drag to swim — the diver follows your finger's movement, not its position, so your thumb never covers the action. Double-tap to burst: a short, invulnerable surge of speed that costs you air.

There is no finish line. There is only the next metre, and how much air you have left.

THE DEEPER YOU GO, THE WORSE IT GETS Descend and the water turns against you. You fall faster. Hazards crowd in and move quicker. Pressure eats your oxygen. Oxygen tanks get scarcer. The light fails, until you are reading the water by the glow of the thing about to hit you.

Jellyfish drift into your path. Barracuda run you down. Eels whip out of the dark. Mines sit and wait. And somewhere past the depth where most divers turn back, an anglerfish is waiting.

BANK IT OR LOSE IT Gems are only yours once you surface, so every metre is a bet. Snag oxygen tanks to stretch the run. Ride a speed boost straight through a wall of hazards. Chain boosted hits to shatter what would otherwise have ended you.

SIX SLOTS, FOUR TIERS, A LOT OF DIVES Spend your gems on permanent gear: Dive Helmet, Speed Fins, Oxygen Tank, Dive Suit, Grip Gloves and a Lucky Charm. Every slot climbs from Basic through Steel and Titanium to Abyssal, with five refinements inside each tier — bigger lungs, faster fins, a tougher suit, a longer reach, a brighter lamp, richer hauls. Recover blueprint shards on deep runs and unlock a whole tier for free.

CHASE THE NUMBER 30 Game Center achievements, from your first dive down to depths most players never see. Two leaderboards: the deepest dive and the richest one. Turn on cloud save and your progress follows you to another device.

STRAIGHT ABOUT ADS No banners. No interstitials. Nothing that interrupts a dive. The only ads in One Breath are ones you choose to watch — to revive a run you were not ready to end, or to double the gems you just earned. Decline and you lose nothing but the bonus.

Free to play, with optional gem packs if you would rather buy a better rig than grind one out.

Leaderboards, achievements and cloud save are all off until you switch them on. Nothing is sent anywhere unless you ask for it.

Take a breath. Go under.
