[[File:Pollution.png|400px|thumb|Example of ingame pollution (red squares) in the map]]
Pollution is represented as an abstract "cloud", updated [[Chunk|per chunk]] every game second (60 ticks) and visible on the minimap and [[Map]], when [[Alternative view]] is on (default [[Game-Options/Keyboard-Defaults#Alt|Alt-Key]]).

[[Crafting network|It is produced by many buildings]] involved in processing items and spreads outwards at a steady rate.

The [[Enemies#Evolution|evolution factor]] is not increased by the spreading/absorbed pollution, but by the pollution produced by all your [[Pollution_Production#Polluters|machinery]] at every tick. The pollution cloud is used to trigger biter attacks and determines the size of the attacks.

== Pollution spread ==

As soon as a chunk has reached 15.0 pollution it starts spreading in all four cardinal directions at a rate of 2% game second (60 ticks).

e.g. a chunk with 400.0 pollution and 4 adjacent chunks with 100.0 pollution each, raises the pollution in all adjacent chunks by 8.0 while reducing its own pollution by 32.0. But everyone of the 4 surrounding spreads 2.0 pollution "back" to the center chunk, so it only loses 24.0 + [[Pollution_Production#De-polluters|absorbed value]].

== Pollution dissipation==
* Every [[Chunk]] (32x32) of map slowly reduces the pollution it covers (See [[Pollution Production#Chunks]]). So the more the pollution spreads, the more is absorbed.
* [[Tree|Trees]] also absorb some pollution (See [[Pollution Production#Trees]]).
* [[Enemies#Spawner|Spawners]] absorb a great amount of pollution.
* In certain [[Mods]] it is possible to build devices or trees which reduce pollution.

== Native life ==
Pollution attracts [[Biter|biters]] to your factory. [[Biter|Biters]] who find themselves in a polluted area will attempt to reach the source of pollution and destroy it.

Each [[Biter#Spawners|spawner]] absorbs 20 + 0.01 * [chunks pollution] every game second (60 ticks), if the chunks pollution is greater than 20 otherwise it absorbs the total pollution.

Higher pollution values decrease the time it takes for biters to join the attack force. After a certain amount of pollution is absorbed the spawner sends one of its biters/spitters to a rendezvous point. Every 1 to 10 minutes (random) the mustered biters launch an attack. If not all biters have arrived at the rendezvous point by that time, they will wait up to an additional 2 minutes for stragglers.

Required pollution to add an additional biter/spitter to the attack wave:
{| class="wikitable"
! Pollution !! Type
|-
|200 || Small biter
|-
|1000 || Medium biter
|-
|4000 || Big biter
|-
|20000 || Behemoth biter
|-
|200 || Small spitter
|-
|600 || Medium spitter
|-
|1500 || Big spitter
|-
|10000 || Behemoth spitter
|-
|}

With 1350 absorbed pollution at the time of attack the following wave consists of 6 small biters and 1 medium biter OR 6 small spitters and 2 medium spitters depending on the spawner's type and [[Biter#Spawn_chances_by_evolution_factor|evolution factor]].

== Modules ==
[[Module|Modules]] that list "+x% pollution" increase pollution multiplier, not a flat pollution rate. Final pollution value is (pollution multiplier * energy usage multiplier * base pollution), meaning heavily boosted buildings are likely to account for most of the pollution produced in a factory.

Multiplayer

Simplypeachy: Link replacement, typos, grammar

{{Languages}}

The multiplayer feature was introduced with version 0.11.X and will be thought only for ''Lan-parties'' or ''Low-latency internet'', as there was a noticeable lag between character actions and those actions happening. As of version 0.12.0 the game features "latency hiding" mechanics which make the lag less noticeable.

The game is technically a peer-to-peer game. Which means, there is no ''server'' needed, but there is support for a "dedicated" server.

Anybody can join an existing game, if he knows the IP of the game. He connects to the game, the game stops and the second players game downloads the current map. If the first host stops, the second player can continue to play and the first player can rejoin at any time. If the game desynchronizes, the map is re-downloaded automatically and the game can continue.

== Playing over LAN / Internet ==

Playing over Internet was not thought to work properly with version 0.11. Noticeable lag could occur depending on connection speed/reaction time. This has become less of an issue with the latency hiding mechanics introduced in version 0.12, but can still cause issues if there is a significant latency between players.

* Both game instances need the installation of exactly same game-versions and mods. (Tip: Maybe someone has the scenario pack mod off?)
* For a more fluid game the "clients" can turn off autosave.
* Factorio uses the port '''34197'''. The port can be changed in the [[Application Directory|config]].
* Factorio uses '''UDP only,''' so make sure, you configured your router correctly. (The game builds it's own "reliable delivery" layer built on UDP to deal with packet loss and reordering issues.)
** Make sure, that there is no firewall or anti-virus blocking the UDP-packets.
** read further, look into "more guides", to configure your router set up.
** It is necessary that all of the peers can communicate with each other. It is however in theory not necessary that all the peers have public IP address - this should work even behind a NAT. See [https://forums.factorio.com/viewtopic.php?f=30&p=51201#p50553 Cube in ''Cannot Have 3+ Players connected at the same time.]''
* The hard limit for the number of players is [https://forums.factorio.com/viewtopic.php?f=53&t=6481&p=50661#p50586 65535]. :)

=== Voice Chat ===
* it is recommended to use voice chat (TeamSpeak, Skype), because you need to talk a lot (coordinate connection, building, handling attacks...). TeamSpeak servers are posted in the [https://forums.factorio.com/viewforum.php?f=53 multiplayer forum].

=== Finding other Peers ===

* use the [https://forums.factorio.com/viewforum.php?f=53 multiplayer board in the forum].
* many players use other software like Hamachi or Evolve to meet other players. This has the "advantage" of creating a virtual private network between the players. See down under software.
* some use also [https://forums.factorio.com/viewtopic.php?f=5&t=9136 Steam] to find others.

== Factorio servers or Why Peer-to-Peer? ==

There were some discussions about, why Factorio doesn't use the client+server-model, but instead uses the peer-to-peer priniciple.

As of version 0.12.X there is support for a Dedicated Server option, but this still functions with the same peer-to-peer networking.

== Dedicated/Headless server ==
{{Experimental|0.12.X}}

As of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the '--start-server' command line option.

In this mode:
* Graphics are not initialized (faster start up, less memory usage, works on completely headless servers)
* Game starts immediately and loads a save given as a parameter to the command
* The server has no character in game
* Game is paused while there are no players connected
* Saves the game on exit (and autosaves normally)

You will need to create your save file before you start the server, as the dedicated server REQUIRES a save file to be provided. This can easily be done by loading up a game in Single-Player and saving it right away.

Below are basic instructions for starting a dedicated server on Windows and Linux.

==== Windows ====

* Go to your Factorio.exe folder (Probably 'C:\Program Files\Factorio\bin\x64\')
* Create a text document and write into it 'Factorio.exe --start-server YOURSAVEGAME.zip'
** If you haven't already done, replace YOURSAVEGAME with your savegame name
* Save the file as server.bat. Important: At 'Save as type:' select 'All Files'
* Use the server.bat to start your server.
* The console log will be shown in the window.
* To close the server, select the console window press Control+C. If you just close it without pressing this, it will not save your game.
* Forward Ports: You will find detailed instructions for your specific router on the web

==== Linux ====

This step-by-step guide has been verified on fresh CentOS 7 and RHEL 7 installs but should be applicable with little to no changes on most distribution.

The guide assumes you will install the headless server under '''/opt/factorio''', adjust paths according to your own setup. We will also suggest that you run the Factorio server as a separate user to harden security of your setup.

This guide does not handle firewall/port forwarding since this can be done in various ways on Linux (make sure to read up how this is done as a Linux admin on your particular distribution)

You can use the [https://github.com/Bisa/factorio-init Linux factorio-init script] to start/stop your headless server in a much better way. The script will ensure you only ever use the most recent save when your server starts (even if that was an auto-save) while also letting you set a number of other settings like Autosave frequency and Latency settings. This script will also simplify updating the server when combined with the [https://github.com/narc0tiq/factorio-updater Linux factorio-updater script].

* Download the at least v 0.12.0 [https://www.factorio.com/download/experimental Experimental Version] and upload the linux tar.gz package to your server /tmp
* Extract the package to /opt/factorio
<nowiki>#cd /opt/
#tar -xzf /tmp/factorio.tar.gz</nowiki>
* Check the binary to find if you need any libs installed
<nowiki>#ldd /opt/factorio/bin/x64/factorio
libasound.so.2 => not found
libX11.so.6 => not found
truncated ....
</nowiki>
* Install each of the missing libs, i.e the ones labelled "not found" using your distro's package handler
** It will ask to install graphics and audio libraries as well, but will not use them in headless mode.
<nowiki># yum whatprovides libasound.so.2
alsa-lib-1.0.28-2.el7.i686 : The Advanced Linux Sound Architecture (ALSA) library
Repo : base
Matched from:
Provides : libasound.so.2

# yum install alsa-lib libX11 <and all other "not found" libs in your case</nowiki>

* Add a new user to your system and assign ownership of the Factorio dir to it (please, do not run as the root user)
<nowiki>#useradd factorio
#chown -R factorio:factorio /opt/factorio</nowiki>

* Try the binary
<nowiki>#su factorio
#/opt/factorio/bin/x64/factorio --start-server savename</nowiki>
As long as it fails saying it cannot find/open the savename.zip you are set! Just upload a save from your own computer and put it in the /opt/factorio/saves directory

==== Dedicated/Headless server in version 0.11.X ====

It was still possible to achieve a Dedicated server in version 0.11.X, but it required some workarounds.

Workarounds in version 0.11.x:

Turret

2015-10-10T17:07:27Z

Simplypeachy: Spelling, grammar fixes and re-writing some sentences to improve readability.

{{Languages}}
'''Turrets''' are defensive structures that can be crafted after being researched. They come in two different tiers with different health, shooting speed, range, ammunition, damage type and damage per shot.
-----

__FORCETOC__

== Gun Turrets ==

Gun turrets are very basic and cheap defensive structures and the easiest way of automatic defense. They use magazines as ammunition which can be refilled manually or by [[inserters]] and mean that enemies cannot have resistances to their attacks. They do not require power and can operate practically anywhere as long as they have sufficient ammunition. Fully upgraded and provided [[piercing rounds magazine]] they can potentially deal more damage than laser turrets ([http://www.factorioforums.com/forum/viewtopic.php?f=16&t=4363&start=20 see thread]) but suffer a reduced range. The gun turret damage upgrade stacks multiplicatively with the bullet damage upgrade. Fully upgraded this means 2.2*2.2=4.84 times as much damage; 9.68 damage with regular bullets or 24.2 damage with armor-piercing bullets. An armor piercing bullet kills small enemies in one shot, and deals more damage to a heavy biter/spitter than a laser shot does.

== Laser Turrets ==

Laser turrets are an advanced defense building with a longer range, good damage and use [[electricity]] to operate (and when idle). Dealing '''laser damage''' they don't face any resistances ([[enemies]] receive full damage) but have a lower rate of fire than gun turrets.
