# Structures

Structures are the foundation of your operations in Pulsar. They enable production, defense, resource processing, and strategic planning.

Each structure serves a specific purpose and contributes to your overall progression:

* [**Mothership**](https://wiki.pulsar.game/assets/structures/mothership)**:** The core of your base. It controls land ownership, unit population, and serves as the central command hub.
* [**Units Factory**](https://wiki.pulsar.game/assets/structures/units-factory)**:** Produce your combat and utility units.
* [**Turrets**](https://wiki.pulsar.game/assets/structures/tesla-turret)**:** Automated defensive structures that protect your Land from alien invasions and enemy attacks.
* [**Refineries**](https://wiki.pulsar.game/assets/structures/pulsar-refinery)**:** Convert raw resources into refined materials used for upgrades, construction, and progression.

Efficient base building and structure management are key to surviving and thriving in the Pulsar universe.
