Navigating the complex subterranean environments of Oxygen Not Included demands a meticulous approach to resource management and colony design. Players must balance atmospheric pressure, thermal expansion, and nutritional requirements to prevent their Duplicants from meeting a premature end. Implementing a few foundational strategies can dramatically increase the lifespan of your colony and prepare you for late-game expansion.
Establishing Efficient Base Layouts
Designing a highly structured home base early on minimizes transit times and optimizes gas behavior throughout your living quarters. Creating standardized vertical shafts with ladders and poles allows gases like heavy carbon dioxide to sink naturally away from your primary facilities. This configuration ensures your duplicants spend less energy running back and forth between tasks and more time building critical machinery.
Furthermore, setting up specialized rooms such as barracks and latrines provides significant morale boosts that keep stress levels low. Isolating your living spaces from the harsh industrial zones prevents toxic fumes from disturbing daily routines. Proper placement of doors and pneumatic tiles helps regulate internal airflow effectively across all core chambers.
Securing Sustainable Food Production
Relying solely on starting wild plants or basic mush bars will rapidly drain your initial water reserves and lead to starvation. Transitioning to organized mealwood farms provides a reliable source of nutrition, but you must ensure you have at least five plants per Duplicant to stay safe. It is vital to construct these agricultural plots in lower sections of your base where carbon dioxide naturally accumulates to keep them stable.
As your colony stabilizes, moving away from simple farming toward ranching creatures like Hatches can supply high-quality meat and coal resources simultaneously. This multi-layered approach keeps your food inventory stocked while generating helpful side products for your infrastructure. Maintaining a diverse food economy prevents a single resource shortage from ruining your entire survival run.
Mastering Oxygen and Atmospheric Regulation
While early-game oxygen diffusers offer an immediate fix for thin air, they consume precious algae reserves that eventually run dry. Transitioning to advanced electrolyzer setups is essential for long-term sustainability as they convert renewable water into breathable air and hydrogen gas. Capturing the rising hydrogen allows you to feed specialized generators, offsetting the electrical cost of your life support systems entirely.
Managing the extreme heat generated by these oxygen production systems is another critical obstacle that requires careful positioning. Building your ventilation hubs near naturally cold biomes or routing gas through insulated pipes prevents your farm areas from overheating. Keeping your core temperatures balanced ensures your crops continue to grow without interruption.
Managing Power and Waste Networks
Relying entirely on manual wheel power wastes valuable labor hours that could be spent expanding your industrial borders. Moving toward automated coal or natural gas grids frees up your workforce to focus on high-priority construction and excavation projects. Integrating smart batteries into your electrical wiring prevents fuel waste by shutting down generators once power limits are reached.
Equally important is the creation of a closed-loop plumbing network that effectively purifies polluted water from toilets and sinks. Directing greywater through water sieves allows you to reuse the resource for basic hygiene without wasting fresh liquid reserves. Proper liquid management safeguards your colony from dangerous germ outbreaks and ensures resource longevity.
