Structure Construction and Maintenance

Planets can support one of each type of structure. They cost [ManualPlanetWarsEconomy#Metal energy] to build and [ManualPlanetWarsEconomy#Energy energy] to function. Anyone can build a structure on any faction-held planet. The output of that structure, if any, is added to your resource [ManualPlanetWarsRoles#Quota quota]. Once built it requires a few turns to become active. Larger, more expensive structures take longer to power up.

All structures, except energy producers and the basic wormhole, require [ManualPlanetWarsEconomy#Energy energy] to function. They will shut down and become non-functional if there is insufficient energy. [ManualPlanetWarsRoles#Roles Economic leaders] can set energy priorities for each structure to control which structures are kept running during a brownout.

Structures are disabled when destroyed ingame or if a successful invasion occurs on their planet. A structure disabled by an attack or power loss requires a few turns to reactivate. This time is twice as long as their initial activation time.

Structures can be destroyed by bomber attacks or scrapped for half their metal cost.

Structure Types

Here is a complete list of structure. This list, alongside extra information, is available in the Structures tab on any planet.


Energy structures are required to power most other structures


Defenses hinder the effectiveness of attacks by reducing Influence gains, destroying bombers or preventing them from warping to the planet in the first place.


Wormholes project influence to nearby planets. This ability can be upgraded, blocked or sent over vast distances. The expensive String Connector is capable of permanently linking two planets.


These structures produce the tools of war.


Some structures would only be found in the lair of an evil genius.


Planet governors may confiscate structures built by other players on the planet. They must pay the metal cost of the structure to the previous owner.

[ManualPlanetWarsRoles#Roles Faction leaders] with [ManualPlanetWarsRoles#Quota metal quotas] may confiscate structures belonging to faction members anywhere, without compensation.
