Oxygen Not Included Beginners Guide Base Building And Survival Tips

Starting a colony in Oxygen Not Included can be an overwhelming experience for newcomers as they attempt to balance oxygen production, food supplies, and temperature control inside an asteroid. Navigating these interconnected mechanics requires deliberate planning and early stabilization strategies. By establishing strong base layouts and prioritizing vital life support systems, new players can easily set their duplicants up for long-term survival.

Establishing an Efficient Base Layout

Designing a logical layout early on prevents unnecessary travel times and keeps your colony organized as it expands. Try to build rooms using a structured grid system with three-tile-high spaces to allow for proper airflow and decoration placements. Grouping functional rooms like bedrooms and washrooms together helps maximize morale bonuses while streamlining daily duplicant routines.

Central vertical ladders with airflow tiles on either side will significantly improve gas circulation across different floors. This design allows heavier gases like carbon dioxide to sink safely to the bottom of your colony while lighter oxygen rises to living areas. Keeping industrial machinery away from primary living zones also protects your duplicants from excessive heat and stress.

Managing Life Support and Oxygen Supply

Maintaining a breathable atmosphere is the most crucial requirement for keeping your colony alive during the early cycles. Algae Deoxidizers provide an excellent immediate solution for oxygen generation, though they rely heavily on finite algae deposits. Transitioning to Electrolyzers later ensures a renewable air supply, provided you manage the byproduct hydrogen and heat effectively.

Monitoring gas pressure throughout your base prevents duplicants from suffering from popped eardrums or suffocation. Utilizing basic gas filters and automated ventilation networks helps isolate harmful gases before they spread into sleeping areas. Setting up a dedicated carbon skimmer at the base of your colony will permanently eliminate excess carbon dioxide build-up.

Securing Sustainable Food and Power

Securing a reliable food source early prevents sudden famines that can quickly end a promising colony run. Mealwood crops grown in planter boxes offer an easy early food supply, though they require steady dirt and comfortable temperature ranges. As your population grows, diversifying into farms with higher-tier crops or ranches for livestock ensures higher morale and better nutrient density.

Power generation should start with Manual Generators to build up early battery storage without producing excess heat. Transitioning to Coal Generators provides consistent power, but requires smart automation to prevent fuel waste. Connecting smart batteries to your generators via automation wires ensures they only run when energy levels fall low.

Controlling Heat and Duplicant Stress

Heat management is often a silent colony killer that sneaks up on players after several dozen cycles pass. Machinery, power generators, and industrial facilities continuously radiate heat that can eventually wilt crops and cause heat stroke. Placing insulated tiles around hot biomes or heat-generating rooms creates a vital thermal barrier for your main base.

Keeping duplicant stress levels low is equally important for maintaining productivity and preventing destructive tantrums. Providing clean mess halls, private bedrooms, and adequate leisure time ensures your crew stays happy and motivated. Balancing task schedules alongside proper hygiene facilities creates a safe and sustainable underground habitat.
