Moon base

In brief: “Moon base” — a building of the “Fields” category in Xterium, available from the start of the game, maximum level — 30.

(data current as of 2026-05-22, game version 2.12.7)

Since the Moon does not have an atmosphere, closed domes have been built for the existence of maintenance personnel. The lunar base produces oxygen, heat and gravity, creating conditions for the life of the colonists. With each level of development, the living space of the biosphere increases by three units.

Description

What it is and why you need it

Moon base — a building from the “Fields” category in Xterium. Main effect — fields on the moon. Unlocks building on the moon and adds fields (3 per level). Moon fields can also be increased another way — via the Planetarium: it raises the moon's diameter for Star Ore, and at certain diameters extra fields unlock.

When to build

Available from day one.

What to watch out for

  • No energy required. The building runs autonomously and does not load the planet's energy balance.

If something is missing — where to look

Contextual alternatives for specific problems. Each block is a separate problem and the buildings that solve it.

If there's still not enough space on the moon

Also: Each level of the Moon Base adds fields. If all levels have been unlocked, you'll need to create a new moon on another planet using the Collider or through a natural collision.

Terraformer

A terraformer on a planet is for regular fields. A lunar base unlocks an entire section of the moon: sensors, a teleporter, and special structures.
