Oxygen Not Included (2019)

Klei's subterranean survival manager transforms thermodynamic principles and fluid dynamics into an all-consuming routing puzzle. Balancing high-pressure gas ventilation, insulated liquid coolant loops, and automated conveyor rails requires meticulous engineering to prevent catastrophic cross-contamination. Watching chilled oxygen circulate steadily through complex ducting networks whilst waste water filters smoothly into closed farming cycles produces an exceptional state of operational flow.
