About Oxygen Not Included
Klei Entertainment released Oxygen Not Included on July 30, 2019 for PC, Linux, and Mac. This indie simulator tasks you with managing a colony of Duplicants trapped inside an asteroid. You start with basic resources and must expand your underground base while keeping your crew alive. The game demands constant attention to gas management, temperature control, and waste processing. It is a complex strategy title where every breath you take requires calculation. You will build pipes, dig tunnels, and automate systems to stop your colony from suffocating or overheating before finding a way to thrive in this hostile alien environment.
Gameplay
You play as an overseer who issues orders to a team of Duplicants. These workers follow paths you create while digging through rock layers and constructing facilities. A typical session involves checking resource levels for oxygen, water, and food every few minutes. You must design ventilation systems that move gases away from breathing zones and manage heat exchange to prevent your base from melting. Automation comes later as you set up logic gates to sort items or trigger machines based on specific conditions. The controls feel precise when placing tiles or connecting pipes, but the real challenge lies in predicting how a small leak will cascade into a disaster within hours.
What Players Think
Players on PlayPile have given this title solid marks with an IGDB score of 78.3 out of 100 based on 126 ratings. The community finds the experience engaging enough to stick with it, though the difficulty creates a steep learning curve. Average playtime reflects this depth as users spend significant hours troubleshooting their setups. Only 50 achievements exist in the game, and the average unlock rate sits at just 11.3%. The rarest achievement "The Lab: Life Found A Way" appears for only 0.20% of players, showing how few reach that specific milestone. Most users express a mix of frustration and satisfaction when their complex systems finally work correctly without collapsing.
PlayPile's Take
This is a challenging simulation that demands patience and logical thinking rather than reflexes. The single-player mode offers deep strategic depth but lacks the social chaos some might expect from a colony builder. At its current price point, it remains a solid buy for strategy fans who enjoy complex management tasks. You will unlock 50 achievements if you persist long enough, but be prepared for many failed attempts before success. This game suits players who like reading detailed tooltips and solving engineering problems without time pressure. Avoid it if you want fast-paced action or simple mechanics that require no planning.
