Oxygen Not Included

Oxygen Not Included is a unique simulation game that challenges players to survive in an unforgiving underground world. Set inside a small asteroid, the game places players in charge of a group of colonists who must build, manage, and expand a livable base while dealing with limited resources. What makes the game stand out is its focus on survival through science, planning, and problem-solving rather than action or combat.

At the core of Oxygen Not Included is resource management. Players must carefully control oxygen, food, water, and power to keep their colony alive. Oxygen, as the title suggests, is one of the most critical elements. Poor airflow design or careless expansion can lead to suffocation, forcing players to think strategically about ventilation systems. Every tunnel dug and machine placed affects how gases move through the base, making even simple decisions important.

Another defining feature of the game is its realistic approach to physics and chemistry. Liquids flow, gases rise or sink depending on density, and temperature spreads through materials. These systems interact constantly, often creating unexpected challenges. For example, machines generate heat, which can damage crops or overheat equipment if not managed properly. Players must learn how to use cooling systems, insulation, and smart layouts to maintain balance.

The colonists, known as duplicants, add personality and unpredictability to the game. Each duplicant has unique traits, strengths, and weaknesses. Some work faster, while others may struggle with stress or have odd habits. Managing their needs, such as sleep, morale, and hygiene, is just as important as managing physical resources. Ignoring these needs can lead to stress reactions that disrupt the entire colony.

Oxygen Not Included is also a game about learning through failure. New players often face colony collapse due to food shortages, overheating, or oxygen loss. However, each failure teaches valuable lessons. The game encourages experimentation and rewards patience. Over time, players develop better designs, smarter systems, and a deeper understanding of how everything connects.

Visually, the game uses a simple but charming art style that makes complex systems easier to understand. Clear animations and detailed overlays allow players to monitor gas levels, temperatures, and power usage. Combined with a calm soundtrack, the presentation creates an experience that is both intense and oddly relaxing.

In conclusion, Oxygen Not Included is a deeply engaging simulation game that challenges players to think critically and plan ahead. Its blend of science-based mechanics, resource management, and character care creates a rewarding experience for those who enjoy problem-solving. The game proves that survival is not about speed or strength, but about understanding systems and adapting to constant change.
