Buy Ammo and Oxygen PC key

Ammo and Oxygen is a roguelike shooter with survival elements, set on an unknown planet. You explore dangerous locations and fight alien creatures while trying to uncover what happened. Persistent progression carries between runs, and a cozy hub gives you a place to prepare.

Explore and survive

Explore stations, dungeons, canyons, swamps and permafrost. Each enemy can be a mortal danger, so careful aim, quick reactions and managing your ammunition matter. Explosions can raise the alarm in creature dens, while nights bring greater danger: stock up on oxygen, flashlight batteries and ammo to improve your chances of surviving.

Weapons and progression

The game includes pistols, assault rifles, shotguns, machine guns, grenade launchers and katanas, along with equipment such as night vision, energy shields and sound absorption. You can upgrade weapons in the hub, find shops and secret rooms throughout levels, discover recipes for unique weapons and gain enhancements that transform your character.

Play together

Play solo or in co-op with up to four players. In co-op, you can fight side by side, protect your teammates and share resources.
