: Choose three Duplicants with high skills in Digging, Building, and Research . Avoid negative traits like "Anemic" or "Narcoleptic". oxygen-not-included-v526233-zip
: Use an Algae Deoxidizer or Algae Terrariums early on to keep the air breathable while you research better solutions. Essential Research & Power : Carbon Dioxide (CO2) is heavier than oxygen and will sink
: Once basic research is done, build a Supercomputer for "Advanced Research" (purple bar). This requires 50 kg of water per unit, delivered via a Pitcher Pump . Avoid negative traits like "Anemic" or "Narcoleptic"
: Build a basic bathroom immediately. No guide is complete without mentioning a Latrine (Outhouses and Wash Basins) to prevent food poisoning germs from spreading.
