Navigating the subterranean asteroid in Oxygen Not Included requires careful planning, keen resource management, and a firm grasp of colony survival basics. New players often find the initial cycles overwhelming as they balance oxygen, food, power, and stress. Understanding core mechanics early on makes all the difference in keeping your colony running smoothly.
Managing Duplicant Population Wisely
The most important rule for beginners is to avoid printing too many Duplicants early in the game. While the printing pod offers new recruits every three cycles, accepting them without sufficient infrastructure will quickly drain your food and air supplies.
Keeping your team small—around three or four Duplicants—allows you to stabilize basic systems before scaling up. Focus on choosing starting crew members with complementary skills in digging, building, and research to set a strong foundation.
Establishing Basic Oxygen and Power Systems
Oxygen diffusers are the primary tool for keeping your early base breathable, but they require power and algae to operate. Placing your diffuser near the central living hub ensures that fresh air reaches high-traffic areas.
Because carbon dioxide sinks, dig a dedicated pit below your main living quarters to collect heavy gases harmlessly. Connect manual generators to batteries to supply steady electricity without wasting valuable Duplicant labor.
Securing Sustainable Early Food Sources
Food security is essential for keeping your Dupes healthy and productive during early cycles. Mealwood is the most reliable starter crop because it produces Meal Lice consistently with minimal maintenance.
Aim for roughly five Mealwood plants per Duplicant to prevent calorie shortages. Cooking can wait until power and labor reserves are stable, as raw Meal Lice will sustain the colony safely in the beginning.
Structuring Your Base for Efficiency and Morale
Building standard 4-tile-high floors and a central 3-tile-wide ladder shaft improves both gas circulation and Duplicant movement speeds. Setting up dedicated rooms like barracks, latrines, and mess halls grants essential morale boosts that keep stress levels low.
Always place wash basins near outhouses so Duplicants clean their hands before returning to work or eating. Expanding gradually into nearby biomes helps you gather necessary copper and algae without exposing your colony to extreme heat or diseases.
