Oxygen is one of the three resources in The Planet Crafter required to increase the Terraformation Index score and reach new milestones of biological life. Survivors can increase their Oxygen by constructing a variety of buildings and structures that become available during different stages of development. To build these oxygen-producing facilities, players will need to procure a sufficient amount of materials gathered from the land or produced within refinement machinery in this survival indie game.
Most of the structures that generate Oxygen in The Planet Crafter have several tiers, which indicate the resource amount they produce. For instance, the Algae Generator T2 will naturally produce Oxygen at a higher rate than the Algae Generator T1. Likewise, Vegetube T1 will not make as much Oxygen as the highest level available, T3. Therefore, players will need to ensure they are always using the higher tier or upgraded versions of the structures when possible for the best and most efficient results.

Seeds come in various forms, with rarer seeds producing more Oxygen. Below are the types of seeds that players can find on their journey:
