# Oxygen Level In VRMARS Mobile, the ultimate objective is to transform Mars into a habitable planet by establishing a thriving colony. The first critical step towards this end is the augmentation of the oxygen levels, which are vital for the players' survival and the colony's growth. {% hint style="success" %} **To succeed in VRMARS, players must navigate the challenging conditions and scarce resources of Mars, making strategic decisions to sustain optimal oxygen levels.** {% endhint %} The availability of oxygen can be elevated by utilizing the resources acquired through the AR system, such as water from ice caps, aluminum from aluminum mines, and iron from iron mines, to craft Oxygen Tubes in the Oxygen Workspace. By elevating the oxygen levels, players concurrently enhance the terraformation index of their land, increasing their Land XP. This progression signifies the player's advancements towards making Mars a more livable planet and is a central aspect of the game's objective. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
