Life support and hostile climates
Check oxygen, suit energy and hazard protection before stepping outside. One full reserve does not replace the other two.
These guides describe the October 23, 2026 development version. The older download with the same version number is missing later features.
Explanatory diagram based on the cited report; not an in-game interface or a spatial construction plan.
Check three reserves
The Exploration Harness stores oxygen, suit FE and hazard protection on the harness itself. Gear tracks equipment and timers; worn spare canisters automatically refill the harness. Empty items do not imply filled reserves. Armor remains separate.
| Environment / mechanic | Reported default |
|---|---|
| Breathable atmosphere | No atmospheric oxygen drain |
| Thin atmosphere | 0.5 oxygen unit/s before modifiers |
| Toxic atmosphere or vacuum | 1 oxygen unit/s before modifiers |
| Combined unmitigated hazard | Capped at 4 protection units/s |
| Vacuum with no oxygen | 2 HP/s suffocation |
| Unprotected environmental damage | Capped at 2 HP/s |
| Respawn grace | 60 seconds |
| Ordinary filter / thermal module | Removes 75% of its applicable category |
| Ordinary jetpack | 25 FE/tick; 80-tick burst; 40-tick recovery |
Protection can regenerate when no hazard applies and suit energy can pay. Ceramic Lining is a stronger thermal replacement; Abyss Harness reduces underwater oxygen use. The Stellar armor set changes jetpack behavior. Fall damage depends on impact speed and gravity.
Match protection to the route
Heat sources, cold blocks, depth, cover and climate machines contribute to thermal sampling, with caps. One fire does not cancel an extreme environment. A sealed regulated room removes thermal hazard. A Protection Field provides hazard shelter without producing breathable air.
Space and the Event Shelf combine vacuum and extreme cold. Underwater travel requires suitable sealed harness support or a working powered Underwater ship module. The environmental classifier treats Nether and End as breathable/temperate; vanilla hazards there remain.
Use habitats for sealing, weather for event load and outbreak medicine for exposure routes. Oxygen protection does not imply infection immunity.
