Oxygen and survival systems: what is confirmed

How breathing, temperature, equipment, food, and environmental danger fit the confirmed game loop—without invented timers.

Breathing defines exploration range

The official store description explicitly tells players to keep breathing and presents the spacesuit as something that can be upgraded. That makes oxygen capacity and the return journey central questions for exploration, even though current official material does not publish exact timers or upgrade values.

Temperature is a second environmental limit

Breathedge 2 also confirms areas with extreme temperature. Equipment is described as protection that helps the player enter new places, so progression is not only about travelling farther; it also involves surviving conditions the starting loadout may not handle.

Launch checklist, not launch claims

Once Early Access is playable, this page will verify the HUD warnings, failure thresholds, refill options, food effects, suit protections, and which upgrades materially extend a trip. Until then, no numerical oxygen route or best survival build is presented as fact.
