Early Game Guide: Efficient Start & Priorities

The early game sets the foundation for a stable colony: secure breathable air, a reliable food source, basic power, fresh water, and room to research critical tech. Proper early choices minimize stress, wasted resources, and heat/germ problems that compound later.

Priorities and pacing

• Oxygen and Breath: keep duplicants in breathable conditions. Duplicants gain/lose Breath at 0.9%/s; they interrupt activities when Breath drops to ~72.7%, get a suffocation warning at ~45.45%, and die if Breath reaches 0% (about 110 seconds after reaching 0). Early oxygen sources: Oxylite near the Printing Pod, Algae Oxidizers/Oxygen Diffusers, Algae Terrariums, or Polluted Oxygen → Deodorizer conversions. Plan a short-term algae solution while researching Electrolyzers or Deodorizers.
• Food and Calories: a duplicant needs ~1,000 kcal per cycle (max 4,000 kcal, hungry at 3,000). Mealwood is the simplest early plant (Meal Lice), requiring dirt and no irrigation; Mealwood yields about 200 kcal/cycle per plant (600 kcal per harvest / 3 cycles), so plan several plants per dupe or cook to improve efficiency.
• Water: water is essential for research, hygiene and many oxygen/food techs. Protect any clean water you find—polluted water is usable but harder to manage. Use Pitcher Pumps and cisterns in hazardous biomes (Swamp starts).
• Power: Manual Generators provide reliable, resource-free power at the start but consume duplicant time. Use Batteries to smooth demand and set good battery thresholds so duplicants run the generator efficiently. Solar plus Smart/Manual generator automation is a viable early hybrid if you want to conserve labour.
• Research: prioritize Research Station early. Place it under Printing Pod light for the +15% work speed area if you need faster research. Ration water used by research buildings until you secure a steady water source.

Early infrastructure layout

• Central work hub: place Research Station, Manual Generator, and one cooking option (Microbe Musher or Electric Grill if necessary) within the Printing Pod light radius to benefit duplicant speed and morale.
• Airflow & gas management: separate CO2 sinks from oxygen production. Carbon dioxide is produced by duplicants (approx 1.2 kg/cycle total) and some early machines; let it settle in low rooms or use a scrubber/deodorizer when available. Avoid sealing high-CO2 pockets where duplicants must work.
• Movement: ladders are cheap and let you reach new areas; duplicants climb slower on ladders than on flat tile but ladders let you save tile construction costs. Remember duplicants need two tiles of height to pass; plan corridors and staircases accordingly.
• Temporary heat sinks/insulation: natural tiles and unmelted natural masses store heat and act as buffers. When dealing with hot geysers or generators, surround installations with natural tile or use materials with high specific heat (Steel, Wolframite) to postpone active cooling.

Early food strategies

• Mealwood farms: quick, low-maintenance. Expect about five Mealwood plants per duplicant if you feed raw Meal Lice, fewer if you cook into higher-quality food.
• Hatches: a ranched Hatch can be slaughtered for meat or kept for eggs. Hatches provide a renewable early meat source; their eggs/meat yield make them an effective mid-early food plan if you can build a stable.
• Wild plants and special starts: Swamp starts may require using polluted water crops or early wild food like Swamp Chard or Grubfruit — process or cook such items into preserves to extend shelf life.

Early power options and management

• Manual Generator: mandatory early; place near breathable air and ventilated CO2. Use battery threshold adjustment to control duplicant trips.
• Coal/Wood generators: research unlocks Tier Two generators. They produce CO2 and heat; avoid placing them inside living areas.
• Batteries: use Batteries and Jumbo Batteries when unlocked. Smart Batteries allow automation to prevent wasteful generator runs.

Germs, sanitation, and health

• Duplicant health starts at 100/100; wounds reduce Athletics (Light: <85, Moderate: <66, Severe: <33) and injured duplicants run slower. Incapacitated dupes die after 120s unless rescued.
• Early sanitation: build lavatories and showers when possible; maintain hygiene to avoid infection. Use Chlorine or Radiation (where available) to disinfect high-germ materials—Chlorine kills germs in one cycle for items and surfaces.
• Food safety: cook when necessary and refrigerate when available. Cooked food often provides better kcal yield and longer shelf life.

Biome-specific tips

• Temperate / Sandstone starts: best for relaxed early game. Access to Algae, Mealwood, Hatches, and Shine Bugs makes oxygen and food easy.
• Forest start: fewer raw resources but offers Arbor Trees and Pips for longer-term food and lumber; expand outward early.
• Swamp start (Quagmiris): messy but resource-rich. Protect any fresh water and expect early use of polluted water for food. Cold water geysers can aid with cooling solutions.
• Volcanoes and metal geysers: early trick — dump Sand into molten outputs to make Refined Metal / Glass and use sand as passive heat absorption; wall off with Insulated/Obsidian tiles if necessary.

Early research milestones

• Prioritize: basic plumbing (toilets), power regulation (wires, batteries), agriculture (planter boxes/farm tiles), and water/oxygen tech (Deodorizers, Electrolyzers once you have steady water).
• Space-related tech (Spaced Out!): if you intend to use early rocketry, unlock Portable Gases and Space Power as needed; rockets require extra modules (BATTERY MODULE, POWER OUTLET FITTING) and rads to research some space tech.

Early heat and cooling containment

• Use natural tile mass as temporary heat sinks. Mining heated tiles deletes half their mass and removes heat — useful to buy time before active cooling.
• Simple space heaters or Tepidizers can be used short-term; avoid uncontrolled heat buildup near farms or biological critters.
• Ice Maker: an early option to delete heat locally by freezing water; useful when Thermo Aquatuner is not available.

Workforce and scheduling

• Use Schedules: default has Bathtime, Work, Downtime, Bedtime blocks. Bathtime concentrates bathroom use and reduces queues. Proper scheduling reduces bathroom/food bottlenecks.
• Assign tasks: early on, prioritize duplicants with high Construction/Research/Cooking skills for those roles; avoid sending specialists to menial repeated manual generator duty unless necessary.

Quick checklist for cycle 1–10

• Build Research Station and start essential tech.
• Place Manual Generator + Battery; set sensible battery threshold.
• Secure oxygen: use Oxylite and oxygen-producing buildings; vent CO2 into low rooms.
• Start Mealwood farm and/or capture critters (Hatches) for food.
• Build basics: lavatory, outhouse (early), a cot or barracks for sleep, and a Microbe Musher or simple cooking option if starvation risk exists.
• Ventilate and plan for spacing between industrial and living areas to avoid heat/germ/decor penalties.

Keeping these fundamentals under control during the first dozen cycles gives you the breathing room to expand into automation, coal power, electrolyzers, and stable food production. Early investments in layout, research order, and basic sanitation prevent many common midgame crises.
