Oxygen Not Included v676963

Oxygen Not Included is a challenging space-colony simulator that puts you in charge of a small group of colonists stranded inside a massive asteroid. From the moment your duplicants break ground, every drop of water, puff of breathable air and watt of power is a precious resource. Your task is simple to state but fiendishly complex to master: dig out a safe, self-sustaining habitat, keep your colonists fed, warm and mentally healthy, and expand until your little outpost transforms from a fragile refuge into a thriving underground city. Along the way you’ll battle oxygen shortages, toxic byproducts, extreme temperatures and ever-shifting stress levels—all while juggling plumbing, power lines and resource logistics.

Key systems and challenges you’ll tackle:
• Base construction and resource management: excavate soil and rock, allocate materials for walls, floors and machinery, and build intricate plumbing and piping networks.
• Stress and morale: provide leisure areas, comfortable sleeping quarters and good food to prevent your duplicants from cracking under pressure. Each individual responds differently to hardship, so keeping everyone happy is a constant balancing act.
• Temperature control: monitor heat generation and ambient conditions to avoid freezing tunnels or scalding reactors. Mastering insulation, cooling loops and heat exchangers is critical.
• Gas and liquid simulations: design elaborate networks of pumps, pipes and valves to deliver oxygen, water and other fluids where they’re needed most, while removing waste products before they become lethal.
• Power grid management: choose from coal, natural gas, hydrogen or manual generators, then configure circuits to avoid overloads and blackouts.
• Oxygen generation and circulation: use the in-game overlay to watch air currents in real time, regulate carbon dioxide buildup and ensure fresh air reaches every chamber.
• Recycling and sustainability: turn waste into valuable resources—convert polluted water into drinkable supplies, harvest fertilizer and even harness natural emissions from critters to power certain systems.
• Exploration of procedural worlds: each new game creates a unique asteroid layout full of unexpected challenges, resources and biomes. No two colonies will ever face the same underground frontier.

Whether you’re a meticulous planner or an improvisational engineer, Oxygen Not Included offers the satisfaction of watching your designs come to life—and the constant tension of knowing that a single mistake can plunge your colony into disaster. Just remember: in the void of space, forgetting to breathe is not an option.
