$14.99Oxygen Keep the last breath flowing
Oxygen is a survival city builder set after toxic gases thinned the air to almost nothing. You build a settlement around the Oxygen Center, keep it powered and breathing, and keep your people housed, fed and working through frosts, droughts, deadly winds and crack explosions. Steady, systems-heavy survival for colony sim fans who like planning ahead.
Is Oxygen worth it?
Oxygen is worth it if…
- you like slow, careful planning around food, water and power
- you enjoy keeping one fragile settlement alive through harsh weather
- you like assigning workers, researching buildings and growing steadily

Keep the Oxygen Center breathing
Everything circles one machine. The Oxygen Center makes breathable air from underground water, and the power it needs starts with coal before you can shift toward sustainable sources. You place housing, workshops and storage around it, assign workers, and balance water, food, materials and energy so the air never stops.
You stockpile before a frost or drought, then watch the coal pile shrink while the wind picks up. It is a slow squeeze rather than a jump scare, and it rewards careful stocking and dull, sensible backup plans.
Lead tired people through bad weather
Your settlers have basic needs, confidence and education, and better confidence and schooling means better work. You give them homes, steady food and water, put them in workplaces, and research new buildings to lift their mood and output.
Threats arrive on rotation: frosts, droughts, deadly winds and crack explosions. Preparation matters more than reaction, so you gather and produce food, materials and water ahead of time. The tone stays dark and matter-of-fact, with survival measured in stores held over, not enemies beaten.
Search the ruins and grow the town
The world beyond your walls still has survivors and useful wreckage. You detect abandoned places, send a team out to collect food and materials, and invite every survivor you find to join the settlement.
Back home there is research to unlock, new features and buildings to develop, and even dead trees to tend and revive. Growth is gradual: more mouths, more jobs, more things that need power and water. For colony sim fans, that familiar trade of one problem for two larger ones is the whole appeal.
Good to know before you settle in?
What exactly threatens your settlement?
Recurring frosts and droughts force you to stock water and food, deadly winds can sicken workers and disrupt jobs, and crack explosions add sudden damage to plan around. Power is its own threat, since the Oxygen Center depends on electricity that begins with coal.
How do your people improve over time?
Beyond food, water and housing, settlers have confidence and education levels tied to productivity. Researching new buildings and features raises those levels, so schooling and morale become production choices rather than decoration.
What do expeditions actually do?
You spot survivors and abandoned areas, then send a team to gather what is useful and bring new people home. It is a practical way to fill gaps in food, materials and labor without waiting for your own production to catch up.
