Anoxemia

Anoxemia is an underwater exploration game where you control Dr. Bailey and his drone, ATMA, searching ocean caves for scientific samples. You'll navigate tight passageways filled with poison clouds, strong currents, leftover mines, and malfunctioning machines while managing your oxygen supply. The drone offers tools and upgrades to help you reach deeper sections, but you need to locate these enhancements first. Death comes from environmental hazards rather than combat—one wrong move into a toxic drift or current ends your run. The game focuses on careful navigation and resource management as you push further into increasingly dangerous cave systems. Best for players who enjoy methodical exploration with constant tension.
