Structures

Structures are used in Galaxy on Fire: Alliances, and are mainly used to extract resources from planets, as well as house soldiers, ships, good and more. Each structure has a Terran, Nivelian, or Vossk variation. Each structure can be leveled up to 20. With each level, the time it takes to upgrade the structure increases. Details can be found on each building tab.

Planetary Defence=

Laboratory= The laboratory is a research facility for Galaxy on Fire Alliances. An advanced technology structure that provides the ability to research planetary tech and unlocks both ships and carriers types with blueprints.

Each Laboratory can hold up to 3 technology.

In-Game Description
"An advanced technology structure that provides the ability to research planetary tech. Unlocks ship types by providing blueprints and improves basic technologies."

Planetary techs:

 * Carrier MK II ••
 * Fighter MK II
 * Freighter MK II
 * Bomber MK II
 * Interceptor MK II
 * Carrier MK III ••

••Can only be found through missions

Blueprint techs:
NOTE: In order to upgrade blueprint techs to level 10, a level 20 laboratory is required.

Research available by level
Barracks= Barracks allow for the training of troops in the game Galaxy on Fire: Alliances, which are vital for protecting our own planets and the conquering of other planets. The cost and training time for each marine reduces by upgrading the barracks. Shipyard=

In-Game Description
"Constructs carriers and combat ships for our fleet, enabling us to travel to other planets, complete missions and engage in space battles."

Ship and carrier unlocked by level
Void Carrier (Level 20 shipyard) Crystal Extractor= Crystal extractors add crystal resources to a planet's local storage in the game Galaxy on Fire: Alliances. It works automatically and will add resources constantly, even while being upgraded. Crystal is required for high-tech, advanced technology, circuit boards, lasers, sensors, CPUs and special materials. Gas Extractor= Gas extractors add gas resources to a planet's local storage in the game Galaxy on Fire: Alliances. It works automatically and will add resources constantly. Gas is needed for weapons, ammunition, mid-tech, fuel and chemical manufacture. Metal Extractor=
 * Requires a blueprint, which must be recovered and researched in a Laboratory.

Before Construction
"Extracts metal from a planet's surface and stores it for later use."

After construction
"A metal extractor adds metal resources to a planet's local storage. It works automatically and will add resources constsntly. Metal is needed for low tech and solid constructions."

Citadel= Citadels are a new feature of Galaxy on Fire Alliances where artifacts can be found.

Description

Headquaters=

In-Game Description
"The headquarters is the main structure of every planet. It is automatically constructed whenever we colonize or conquer a planet. The headquarters marks a planet as owned and controls all other structures on that planet. Therefore, the headquarters must be upgraded before other structures."

Characteristics
As the description implies, in the game Galaxy on Fire: Alliances, each and every planet has its own headquarters. No structure can be of a higher level than that of the headquarters. Demolishing the headquarters will result in an automatic destruction of all buildings and techs followed by the relinquishment of planet ownership. It is advisable to remove all ships, carriers, troops and resources and relocate them to another planet before doing so.

An interesting feature of the headquarters is that it can act as a slingshot to boost departing carriers. This is possible as the headquarters also provides a travel speed bonus other than acting as a resource storage. A player may relocate his fleet to his own planet or a friendly one that has a high level headquarters before sending the fleet to another system that is far away.
