About O2GETHER Steam Key:

SHARE ONE OXYGEN TANK, SHARE ONE FATE O2GETHER is a 1–4 player co-op survival game set in a debris field between your ship and a distant space station. Your team's air supply lives in a single shared O₂ tank, and it won't move on its own. If you want to survive, someone has to grab it and push. THE TANK IS CARGO, NOT A LEASH There's no rope pulling it along behind you. Getting the tank anywhere means physically hauling it as a team, fighting momentum, spinning wreckage, and hazard strikes that can knock every hauler loose at once. YOUR OXYGEN ALWAYS RUNNING OUT Every player carries a small personal oxygen buffer that drains constantly and only refills near the tank. Peel off to scout ahead or grab a stray item, and you're on a countdown. Make it back in time, or black out until a teammate reaches you. ONE MISTAKE, EVERYONE'S PROBLEM Teamwork comes first. A wasted breath, a bad collision, or a leak left unrepaired tightens the timer for the whole team, not just one person. SEE IT COMING, SURVIVE IT TOGETHER Hazards are visible before you commit to them. Spinning debris, electrified corridors, and meteor showers are all readable from a distance. The chaos comes from actually getting the tank through them. 100+ HAND-CRAFTED SECTIONS, EACH WITH A NEW WAY TO KILL YOU Drifting junk, stray rockets, high-voltage power conduits, meteor showers. Each biome throws its own hazards at your crew, and the Quarantine Zones confront you with all of them at once. Every section is shuffled each run, so you never get the same route twice. Survive them all, then take on Endless, where the delivery never stops.
