About The Game

Ammo and Oxygen is a brutal blend of roguelike shooter and survival horror, throwing you onto a hostile alien planet where every bullet and every breath matters. Exploration takes you through abandoned stations, swamps, canyons, and frozen wastelands, each packed with dangerous creatures that punish careless moves. Daytime battles demand precision and resourcefulness, but once night falls, the stakes rise—oxygen runs low, flashlight batteries drain, and the threat of unseen horrors turns each step into a gamble. The tension between conserving resources and pushing forward makes every encounter feel razor-sharp and meaningful.

Between runs, a cozy hub provides a much-needed breather, letting you upgrade weapons, craft unique gear, and prepare for the next descent into chaos. With a deep arsenal of firearms, explosives, melee options, and high-tech gadgets, the game offers endless opportunities for experimentation. Co-op play for up to four players adds another layer of intensity, as teamwork and resource-sharing become essential for survival. Ammo and Oxygen thrives on its mix of high-stakes combat and long-term progression, making each run a deadly but addictive fight for survival.
