The Heat Death — Oxygen Not Included Walkthrough

Learn the basics of Oxygen Not Included with this guide, covering starting your base, temperature management, food production, dupe management, and power systems. Essential tips for new players.

Walkthrough
  1. 1
    Starting your base: Utilize overlays (Temperature, Power, Thermal Comfort) to understand your environment. Avoid digging out everything at once.
  2. 2
    Temperature Management:
  3. 3
    Pay close attention to temperature overlays to identify hot and cold spots.
  4. 4
    Locate barracks and bedrooms in temperate areas, away from heat sources.
  5. 5
    Ensure greenhouses maintain optimal temperatures (e.g., Meal lice and Bristle blossom require specific ranges). Exceeding these by even 1°C can halt growth.
  6. 6
    High temperatures can scald dupes, requiring Medbay visits and halting productivity.
  7. 7
    Use materials wisely: Granite/sandstone for decor bonuses (sculptures, paintings, tiles), igneous rock for greenhouses (low thermal reactivity), and abyssalite for its excellent insulation.
  8. 8
    Keep heat-producing elements like power generators and batteries away from greenhouses (below, adjacent, or above).
  9. 9
    Food Production:
  10. 10
    Early Game: Mealwood seeds provide Meal lice (600 kcals, food quality -1). Easy to obtain but require dirt and have low quality, leading to stress in promoted dupes.
  11. 11
    Mid Game: Switch to Bristle Blossoms (produce Gristle berries when cooked: 2050 kcals, food quality 1). Require water and light. Best supported by a coal generator to power lights. Use hydroponic farm tiles to automate watering.
  12. 12
    Alternative: Mushrooms (fried: 2800 kcals, food quality 1). Require polluted water and immersion in carbon dioxide.
  13. 13
    Food Preservation:
  14. 14
    To prevent food spoilage on the floor, ensure greenhouses are filled with carbon dioxide, as germs need oxygen to survive.
  15. 15
    Store food in ration boxes within an ice biome to act as a natural refrigerator.
  16. 16
    Immersing ration boxes in CO2 further prevents decay.
  17. 17
    Dupe Management:
  18. 18
    Dupe Count: Avoid getting too many dupes early on. Aim for a minimum of 3 and a maximum of 6 until you can reliably support them. Too many dupes can lead to insufficient food and oxygen.
  19. 19
    Rooms: Build rooms for bonuses. Barracks increase stamina regeneration, and latrines relieve stress. Consult the Room Overlay for details.
  20. 20
    Stress Management: Stress is a major challenge. Building rooms and providing appropriate facilities is crucial.
  21. 21
    Power: (Covered implicitly through generator placement and greenhouse lighting needs).
  22. 22
    Ventilation: (Mentioned in relation to CO2 management for food preservation).
Tips
  • Always use the game's overlays to assess your environment and plan your base.
  • Material properties (decor bonus, thermal reactivity) are critical for efficient base building.
  • Don't underestimate the impact of temperature on plant growth and dupe comfort.
  • Carefully manage your dupe count to avoid resource strain.
  • Utilize CO2 environments and cold biomes for effective food preservation.
