Oxygen Not Included 744825 for macOS

Oxygen Not Included is a hardcore survival simulator where you manage a small colony of duplicants inside an unforgiving asteroid. You're not just building a pretty base; you're building the systems to keep it alive. It's a game about balancing the breath in their lungs, the food in their bellies, and the happiness in their routines. But this particular brand of chaos isn't for everyone, so here's a straight look at who will click with it and who will bounce right off.

• You'll love it if you enjoy untangling complex, interconnected problems. A surplus of one resource always creates waste, and that waste kicks off a chain of diseases you then have to solve.
• You'll love it if you get satisfaction from watching a messy, near-death camp turn into a functioning machine, complete with relaxation rooms for stressed-out duplicants.
• You'll hate it if you want clear, simple goals. The game never holds your hand as your duplicants turn your asteroid into a polluted nightmare.
• You'll hate it if you can't handle losing. A single overlooked gas pocket or food shortage doesn't just set you back; it ends your whole colony.

This isn't a casual god game. It's a systems-thinking puzzle wrapped in a cartoon skin. If you get a kick out of designing your own solutions to brutal survival problems, this game will eat up your evenings. If that sounds like a chore, best to leave this asteroid alone.

Dig open spaces before building living quarters

The game throws you into a tiny pocket of breathable air and says "figure it out." Here's what I learned after restarting a dozen times.

• Dig open spaces before you build living quarters. Carbon dioxide sinks to the bottom right of your base. If you carve out a deep pit early, the bad air collects there instead of smothering your duplicants while they sleep.
• Keep your outhouses and compost piles away from the water supply. Polluted dirt seeps through tiles faster than you think, and food poisoning in your main reservoir is a slow-motion disaster.
• Limit your duplicants to five or six for the first thirty cycles. Every new mouth pushes your oxygen and mealwood production closer to collapse. The game offers new colonists like candy, but saying "no" is the real skill.
• Build a manual generator and a small battery on day one. Research stations eat power, and a duplicant on a treadmill is a duplicant not digging your latrine trench.

Ignore fancy rooms and decor bonuses until you have stable oxygen diffusers and a surplus of raw mineral. A stressed duplicant with a pretty painting still breaks your plumbing.

Printing too many duplicants crashes your colony

Every colony simulator has a learning curve shaped like a cliff. This one has a few traps that catch almost everyone.

• Printing every available duplicant. The printing pod tempts you with fresh hands, but a colony of twelve with four oxygen diffusers and three mealwood plants starves in under ten cycles. Match your population to your infrastructure, not your optimism.
• Sealing off too early. Players wall themselves into a cozy box, then realize they have no algae, no copper, and no path to a slime biome. Always keep a mining shaft open; the asteroid's resources are finite where you stand.
• Ignoring skill assignments. Duplicants come with traits that make them naturally faster at digging, creative problem solving, or planning. Putting a squeamish duplicant on latrine duty tanks their morale and triggers stress-induced vomiting. Check their character sheet before pointing them at a task.
• Treating gases as an afterthought. Hydrogen floats up, chlorine sits low, and polluted oxygen spreads disease. Without airflow tiles and strategic vents, your base becomes an unbreathable soup that kills quietly while you fuss over a broken massage table.

A friend grabbed the oxygen not included mac download and lost his third colony to a hydrogen pocket he never noticed. The game won't beep at you when the air turns bad.

This release is a hotfix that swats a few annoying bugs and cleans things up under the hood.

• Incapacitated duplicants no longer pull a Houdini and teleport to the bottom left of the world after a rescue and resuscitation.
• Fixed the Masterworks skill text so it correctly points to Masterpiece artwork quality.
• Taking apart a gasket now spawns the right element instead of some mystery material.
• Cleaned up a liquid rendering bug that was giving older graphics cards a headache.
• Removed some unused textures and optimized others to free up memory, plus fixed a pesky navgrid memory leak.

• Runs on Intel and Apple Silicon Macs.
• Interface languages: English, Russian, Simplified Chinese, Korean.
