One Breath: Submarine Dive

Every dive is a choice: explore a little farther, or return with what you have found. Take your small research submarine into the unknown.

One more treasure. Enough oxygen to make it home?

One Breath is an offline underwater adventure where you pilot a small submarine, explore sunken ruins and decide when to turn back. Going deeper is tempting. Bringing your discoveries home takes a plan.

EVERY DIVE IS A DECISION Balance oxygen, cargo and the journey back. Open one more chest or protect what you have found. Choose your own route through the depths.

SIX REGIONS, 30 MAIN MISSIONS Explore underwater passages, wrecks and hidden secrets. Currents, mines, defense systems and marine creatures give you different dangers to read along the way.

TURN DISCOVERIES INTO UPGRADES Spend coins earned on dives to improve your oxygen tank and equipment. Choose your chassis, fit modules, equip a harpoon and prepare for your next expedition.

TOUCH, DRAG, EXPLORE Drag from an empty spot in the play area to steer your submarine. Read your radar and interact with nearby objects using the action button. Adjust left-handed controls, interface size and reduced motion to suit you.

AN OFFLINE, SINGLE-PLAYER ADVENTURE No game account is required. Your progress stays on your device, with save export and import available.

What will you find in the depths—and will you bring it home?
