Oxygen Not Included

This guide provides essential tips for Oxygen Not Included, focusing on starting your base and managing key survival elements. It covers temperature control, food production, managing your duplicants (Dupes), and power generation.

Starting your base:

Use the overlays in the top right of the screen to manage your base effectively. Avoid digging out everything indiscriminately.

Temperature:

• Monitor the temperature overlay to identify hot and cold spots.
• Locate barracks and bedrooms in temperate areas, away from heat sources.
• Ensure greenhouses maintain optimal temperatures for crops like Meal Lice and Bristle Blossoms; even a 1°C deviation can prevent growth.
• High temperatures can cause Dupes to get scalded, requiring medical attention and halting productivity. Use the Thermal Comfort Overlay to see areas safe for Dupes.
• Different materials have varying thermal properties. Granite and sandstone offer decor bonuses, suitable for sculptures and tiles. Igneous rock is good for greenhouses due to its low thermal reactivity. Abyssalite is even better but scarce.
• Keep heat-generating elements like power generators and batteries away from greenhouses.

Food:

• Early game: Mealwood seeds produce Meal Lice (600 kcals, -1 food quality). They require dirt, which is not fully renewable. Suitable for Dupes with low food expectations.
• Mid-game transition: Bristle Blossoms produce Bristle Berries (2050 kcals, 1 food quality when cooked). They require water and light. Use coal generators for power and consider hydroponic farm tiles to automate watering.
• Mushrooms: Grown from fungal spores, fried mushrooms offer 2800 kcals and 1 food quality. They require polluted water and immersion in carbon dioxide.
• Food preservation: If a greenhouse is full of carbon dioxide, food on the floor will not decay as germs need oxygen. Storing food in ration boxes in an ice biome also reduces decay.

Dupes:

• Limit the number of Dupes. Aim for a minimum of 3 and a maximum of 6 initially to ensure sufficient food and oxygen.
• Build rooms for Dupes: Barracks increase stamina regeneration, and latrines reduce stress.
• Manage Dupe stress carefully, as it can significantly impact productivity.

This guide provides essential tips for managing advanced oxygen and water loops in Oxygen Not Included. It covers crucial aspects of base building, temperature control, food production, and dupe management to help you survive and thrive.

Key Areas Covered:

• Temperature Management: Utilizing overlays to identify hot and cold spots, understanding material properties (like granite and abyssalite) for construction, and strategic placement of heat-generating objects.
• Food Production: Transitioning from early-game Mealwood to Bristle Blossoms and Mushrooms, managing water and light requirements, and preventing food spoilage using carbon dioxide environments or ice biomes.
• Dupe Management: Avoiding overpopulation, understanding the importance of room bonuses (barracks, latrines) for stamina and stress, and the challenges of managing dupe stress.
• Base Building: Using overlays for efficient base design and understanding the impact of different materials on decor and thermal properties.
