Buildings in YORG.io are player made structures. These buildings usually require resources to perform their task. Different buildings have different purposes, from utility-based structures to defensive towers. Each building will automatically give their resource to and receive from other buildings if there is a path available.

List of buildings[]


Receives crystals (which function as in-game credit, and can be used to upgrade or buy buildings) from the Crystal Mine. Other buildings can't be upgraded past the base's level. The game doesn't truly start until your base has been placed. The game is lost when the base is destroyed. Protect your base against the invading zombies.

Crystal Mine[]

Mines crystals from crystal orbs. Must be placed next to crystal orb (spiky red gem that gives off small red particles).

Iron mine[]

Mines iron from iron ore deposits. Must be placed next to iron ore (slightly lopsided, sparkly grey stone).


Harvests wood from forests. Must be placed next to tree (lime green 12-sided shape).


Protects your base from enemies by blocking their movement. Can be given shields by the Shield Generator.


Transports resources within its range between buildings. Can be chained. Send resources faster as they are upgraded. These disappear when the instant transport is bought in the skill tree.
