### Building Categories
#### Workshop
The workshop is an economic building used to craft collectibles for **weapons** and **equipment** that players can then use in-game. It’s essential to all galactic adventurers as this building is a significant source of resources to its owners.
Owners can use the workshop to craft items by spending **resources** and use them in-game or sell them on the marketplace.
By upgrading the workshop's level, players will open more crafting opportunities and have access to rarer items.
#### Engineering Bay
The Engineering Bay allows its owners to craft and upgrade utility items such as Extraction Modules and Spaceships that open up PvP mining and combat.
