{{About/Space age}}
A '''captive biter spawner''' is a special production building that is initially unlocked by researching [[captivity (research)]]{{SA}} with [[agricultural science pack]]s{{SA}} and is used to produce [[biter egg|biter eggs]]. A captive biter spawner has no [[module]] slots, is unaffected by [[beacon]]s, and cannot be connected to either circuit or logistic networks. A captive spawner cannot be removed by the player or [[construction robot]]s, but can be destroyed via weapon fire, at which point it will spawn a small biter. Captive spawners are only placeable on [[Nauvis]].

== Biter egg production ==
Captive biter spawners are solely used to produce [[biter egg|biter eggs]], for which they are the only source in the game. Producing biter eggs does not require setting a recipe or providing any ingredients other than a constant influx of fuel in the form of [[bioflux]]. A captive biter spawner can hold a maximum of 100 biter eggs, which they produce at a rate of 5 eggs every 10 seconds, or 0.5 /s. The production cycle continues when the output slot is full, even though no additional eggs are being produced. Biter eggs held in the output slot will not start to spoil until removed.

== Obtainment ==
Initially, the only way to create a captive biter spawner is by firing a [[capture bot rocket]]{{SA}} at a [[Enemies#Nests|biter spawner]] on [[Nauvis]], which will slowly transform the spawner into a captive one. After reaching [[Aquilo]]{{SA}} and researching [[captive biter spawner (research)]], the player can craft captive biter spawners themselves, which can be manually placed. While in the player's inventory or another container, a captive spawner has a [[Spoilage mechanics|spoil time of 30 minutes]], at which point it will turn into a behemoth biter.

== Food consumption ==
A captive spawner requires a constant supply of [[bioflux]]{{SA}}. Starving spawners will stop producing biter eggs and lose health at a rate of 1 per second, regardless of quality. If a captive spawner's health reaches zero, it will transform back into a normal spawner and will have to be captured again.

Previously captured and then starved [[Enemies#Nests|biter spawners]] are normally not targeted by automated weapon systems, including [[turret]]s, [[artillery]], and [[spidertron]]'s automatic rocket launchers, but they will still be targeted by [[capture bot rocket]]s. They still consume [[pollution]] and spawn biters which are affected by the [[Enemies#Evolution|evolution factor]].

[[Bioflux]]{{SA}} is used for food. One item of bioflux has an energy value of 6 MJ, and since the captive biter spawner consumes 100 kW of food, each item of bioflux will last for exactly one minute. With one normal quality item of bioflux lasting for two hours before it [[spoilage|spoils]], this means that 120 items of bioflux of the same age may be consumed by a single captive biter spawner before any of them spoil.

== Quality ==
Captive biter spawners with a higher quality level will ''not'' yield higher quality [[biter egg]]s.

If a captive biter spawner reverts back into a biter spawner for any reason, it will retain the quality it had as a captive biter spawner. This resulting spawner will spawn biters of the same quality, which will have the capability of forming expansion groups that will also retain their quality level upon successful expansion - creating more quality biter or [[Enemies#Spitters|spitter]] spawners, and even quality [[Enemies#Worms|worms]]. Failing to contain such reverted spawners can lead to the planet becoming populated by higher quality enemies.

{{About/Space age}}
The [https://factorio.com/galaxy Galaxy of Fame] is a feature available upon beating Factorio: Space Age. It is a database of saves that have beaten the expansion, able to be viewed on the Factorio website. It appears as a vast galaxy of stars of all size and colors. Each star belongs to one particular player who has beaten Space Age. Clicking on a star will bring up a snapshot of that player's save.

After reaching the [[solar system edge]]{{SA}} and viewing the victory screen, the player will be invited to upload a snapshot of their save to the Galaxy of Fame. Only one snapshot can be uploaded per player; uploading a new snapshot will override the previous one. The player can also include a custom name and comment. After uploading, the game will provide a link to the player's snapshot on the Factorio website.

After winning, the "Galaxy of Fame" button will appear on the main menu. Clicking it will allow the player to upload a new snapshot, or click the link to the existing snapshot.

== Snapshot ==

[[File:Kovarex_gof.png|thumb|600px|right|The Galaxy of Fame snapshot of lead developer [https://www.factorio.com/galaxy/Iron%20I:%20Alpha1-1.A1W3 kovarex].]]

The Galaxy of Fame includes the following information:
* A custom name & comment (optional)
* The date of upload
* Time played
* Game version
* Map seed
* Player count
* List of mods
** This includes both the four mandatory mods (Base, Elevated Rails, Quality, and Space Age) and any user-created mods.
* Map views of the five planets, in the order they were visited
* Map views of all [[space platform]]s{{SA}}, in the order they were created
* A full list of the number of all items produced
* A full list of the amount of energy produced by each [[power production|power source]]
* A full list of the number of kills, including all [[asteroids|asteroid]] varieties

== Star Position ==
The position, color, and size of a player's star is randomized upon upload. Given the vast number of stars in the galaxy, it can be difficult to locate your own star on the map by searching manually. However, each star's position is fixed and will always be in the same place.

Each star is placed by a set of coordinates which can be read to reliably locate it on the map. A star's coordinates can be located within the URL of the snapshot that is provided upon upload. As an example, the following is the coordinates for the snapshot of lead developer Kovarex:

Iron I: Alpha1-1.A1W3

==== Sector ====

The first word of the URL, named after an item, designates one of sixteen sectors within the galaxy, laid out on a grid pattern. The four central sectors, containing the majority of stars (28'900 out of 32'600, as of February 2025), are named Iron, Quantum, Sulfur, and Calcite, and are marked in '''bold''' in the chart below.
The sectors as they are currently known, are laid out like this.

{| class="wikitable"
|-
| Copper || Ammonia || Fluorine || Carbon
|-
| Bioflux || '''Quantum''' || '''Iron''' || Stone
|-
| Lithium || '''Sulfur''' || '''Calcite''' || Electrolyte
|-
| Uranium || Tungsten || Holmium || Yumako
|}

==== Quadrant ====

The numeral after the sector name designates one of four numbered quadrants within a sector. The table below shows the layout the quadrants within the Iron sector as an example. Each sector has its quadrants split up in the same pattern, so the quadrant to the immediate left of "Iron III" would be "Quantum IV".

{| class="wikitable"
|-
| Iron III || Iron IV
|-
| Iron I || Iron II
|}

==== Region ====

The second word, named after a letter of the Greek alphabet, designates a region within a quadrant. Each quadrant contains 9 regions. Their position within the quadrants are structured as follows:
{| class="wikitable"
|-
| Eta || Theta || Iota
|-
| Delta || Epsilon || Zeta
|-
| Alpha || Beta || Gamma
|}

The two numbers after the region name designate the star's location within the region. Each number can go between 1 and 7. The first number increases from left to right, while the second increases from bottom to top. The two of them together position the star within a region. For example, a number of 1-1 designates a position within the bottom left of its region; 1-7 in the top left, and so on.

==== Exact position ====

Following the dot, the final pair of letter-number sets designates the exact position within a region. Letters go from A to G (the first letter) and T to Z (the second), and increase from left to right. The first letter will only be advanced by one when the second letter advances through all 26 letters. For example, A1Z1 comes before B1Y1. Numbers once again go between 1 and 7 and increase from bottom to top. The same rule from letters applies to numbers.

As a final example, a coordinate of Quantum II: Gamma5-1.A7Z1 will give a position as follows:
* Quantum sector
* Bottom right of Quantum II quadrant
* Bottom middle of Gamma region
