Oxygen Not Included is an upcoming space colony survival and simulation video game developed and published by Canadian studio, Klei Entertainment, for Microsoft Windows. Oxygen Not Included is a simulation video game with elements of survival games. At the start of a new game, three colonists find themselves in an asteroid with isolated pockets of breathable atmosphere, with no memory how they got there. The player is tasked with managing and taking care of these colonists as they try to survive and create a sustainable makeshift space colony. To help establish the colony, the player directs the colonists to perform certain tasks, such as mining for resources, growing food, crafting equipment, researching new technologies, and maintaining their own health through nourishment, rest, and hygiene. The player does not control the colonists directly, and instead provides prioritized instructions, from which the colonists will then follow to the best of their abilities. For example, the player can order a conduit of wire to be built; which will have the colonists collect the materials to make the wire, clear away any materials around the conduit's path, and then construct the wire. If the colonists cannot access a source of copper for the wire, the task will remain uncompleted as the colonists go to complete other tasks they can do. Design lead Johann Seidenz said that games such as Dwarf Fortress, Prison Architect, and The Sims influenced the design of Oxygen Not Included.
