Our guide helps players master the intricate systems of Oxygen Not Included, offering observations and comparative advice for each core mechanic without relying on paid upgrades or hidden features.

01 / THE GUIDE

Balancing Resources

Compare early digging speed against resource abundance; note how faster excavation reduces travel time but may increase stress if duplicants are over‑tasked.

  • Prioritize digging near abundant resources to reduce travel time.
  • Set up recycling loops early to offset later shortages.

02 / THE GUIDE

Optimizing Stress Relief

Experiment with different leisure setups and track each duplicant’s stress meter to see which activities yield the greatest morale boost.

  • Provide varied leisure options to suit different duplicant personalities.
  • Upgrade accommodations before stress spikes become critical.

Thermal Management Trials

Place heat‑generating devices in varied locations and record temperature changes, identifying optimal insulation placements.

  • Place heat‑generating machines away from temperature‑sensitive areas.
  • Employ insulation on walls bordering extreme zones.

04 / THE GUIDE

Power Grid Scaling

Start with a small generator, then incrementally add sources while watching circuit load, noting the point where overloads occur.

  • Start with low‑output generators and scale up as demand grows.
  • Monitor circuit loads to avoid accidental overloads.

05 / THE GUIDE

World Exploration Strategies

Generate multiple worlds, map initial resource clusters, and compare how early scouting influences long‑term colony stability.

  • Scout the surface before committing resources to deep excavation.
  • Adapt early strategies to the specific resource distribution of each world.
