En adición a ser un juego para un solo jugador, Factorio también ofrece un modo multijugador, permitiendo que múltiples jugadores cooperen y se ayuden entre sí, o trabajen contra el otro en JcJ. Esta página documenta cómo configurar una partida multijugador y cómo unirte a una. De forma predeterminada, las partidas multijugador ejecutan el escenario de [[Game modes and options/es|juego libre]] CO-OP donde todos los jugadores trabajan juntos para lanzar un cohete con un satélite al espacio. Otros escenarios, incluyendo mapas de JcJ, están disponibles para su descarga en el foro de [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Mapas y Escenarios].


== Creando Una Partida Multijugador ==
Multiplayer games can be joined, hosted while playing, or hosted by a dedicated server.  Multiplayer games can be advertised to other players on the same LAN or worldwide.
Use the ''Multiplayer'' button in the ''Play'' menu to start playing a multiplayer game, choose ''New'' or ''Load'' or ''Scenarios'' to host and play, or ''Browse'' or ''Play on LAN'' to connect to an already-running game. The host can also choose not to advertise the game at all, in which case you'll need the server's (public or otherwise reachable) IP address; you can then ''Connect'' directly to that to join the game.
Notes and tips:
* All game instances need the installation of ''exactly the same'' game-versions and mods.
* Factorio servers use port '''34197'''. The port can be changed in the [[Application directory|config]] file.
* Factorio uses '''UDP only'''. Make sure you configure your router's port forwarding correctly. (The game builds its own "reliable delivery" layer built on UDP to deal with packet loss and reordering issues.)
** Make sure there is no firewall or anti-virus blocking the UDP-packets.
* The hard limit for the number of players is [https://forums.factorio.com/viewtopic.php?f=53&t=6481&p=50661#p50586 65,535]. However, practical limit for this is much lower, popular streamers have managed slightly over a hundred players.
=== Dedicated/Headless server ===
As of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the --start-server command line option. You can run factorio --help to get a list of all command-line arguments that Factorio accepts.
In the headless 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 (though this can be overridden using the --no-auto-pause option)
* Saves the game on exit (and autosaves normally)
''Please note that there has been a slight change between 0.12, 0.13 and 0.14 in how --start-server (and others) interpret the given parameter. Version 0.12 expected --start-server to be followed by a save name, that was to be found in the saves directory. 0.13 instead expects --start-server to be followed by a path to a save file. I.e. if you did '''factorio --start-server foo''' in 0.12, you probably want to use '''factorio --start-server saves/foo.zip''' in 0.13.''
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 using the --create command-line argument. For example:
<pre>
./bin/x64/factorio --create ./saves/my-save.zip      # This creates a new save, as if by clicking the New Game button in the GUI
</pre>
<pre>
./bin/x64/factorio --start-server ./saves/my-save.zip # This starts a server that will host the file created on the previous line
</pre>
There are several JSON configuration files that factorio can make use of to change the server and map settings:
* '''map-gen-settings''' to set parameters used by the map generator such as width and height, ore patch frequency and size, etc. (Added in 0.13)
* '''map-settings''' to control pollution spread, biter expansion and evolution, and more (Added in 0.15)
* '''server-settings''' which consolidated several command-line options into a single file (Added in 0.14.12)
Example files for each of these parameters are included in the data subdirectory.
The --map-gen-settings and --map-settings options must be used with the --create option when you create a new map.  For example:
<pre>./bin/x64/factorio --create saves/my-save.zip --map-gen-settings my-map-gen-settings.json --map-settings my-map-settings.json</pre>
Starting the factorio server requires you to specify the location of the server-settings.json file. By default this is in the factorio data folder. For example to start factorio using the most recent saved map, you would run:
<pre>./bin/x64/factorio --start-server-load-latest --server-settings ./data/server-settings.json</pre>
=== Setting up a Linux Factorio server ===
'''Note:''' Factorio now requires <tt>glibc</tt> version 2.18, but CentOS/RHEL 7 only ship with version 2.17 so this guide will no longer work without [https://forums.factorio.com/viewtopic.php?t=54654#p324493 manually compiling <tt>glibc</tt> 2.18].
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 distributions.
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.
Note that there are two distinct packages for Linux that can be used to run a headless server. First is the usual Linux download, that contains the full game. The other is the special  [https://www.factorio.com/download-headless/stable headless package]. The headless package does not contain any files irrelevant for a pure server, such as graphics and sounds. It is also not linked against libraries that may not be present on a server machine, such as Xlib, libGL or libasound. This option should be selected if running in a 3rd party hosted server.
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 selected package -- either full game or the headless package -- and upload the Linux tar.gz or tar.xz package to your server /tmp
* Extract the package in /tmp to /opt/factorio
<pre>
$cd /opt/
$sudo tar -xzf /tmp/factorio.tar.gz # Use the correct file name. It includes the factorio version number
$sudo tar -xJf /tmp/factorio.tar.xz # if you downloaded a .tar.xz file (ver 0.15.x)</pre>
* Add a new user to your system and assign ownership of the factorio dir to it (please, do not run as the root user, sudo may be needed)
<pre>
$useradd factorio
$chown -R factorio:factorio /opt/factorio</pre>
* Try the binary
<pre>
$su factorio
$/opt/factorio/bin/x64/factorio --start-server savename</pre>
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, or use the --create ./saves/newgame.zip argument.
=== How to list a server-hosted game on the matching server ===
In order to publish the game to the matching server, Factorio needs to be given some more information than just the save file location. These information are provided in a ''server settings file''.
To create a server settings file, look at the example file located in '''data/server-settings.example.json''' in the Factorio [[Application directory]]. The recommended way is to make a copy of this example file and edit the copy.
The following values can be changed:
; Name: This will be the name under which the server will be listed in the server browser
; Description: A brief description of your server
; Tags: A list of game tags
; Max Players: Allows you to limit the number of players that can be connected to the server at the same time. If you want no limit, just set max_players to 0.
* Visibility for server browser: May be either public, LAN or hidden.
** Public: The server will appear in the public server list. This requires the login credentials below to be filled in.
** LAN: The server will not appear in the public server list, but will be available through the Play On LAN button
** Hidden: Clients will have to connect using the server's IP address
* User credentials using a username and password or authentication token (found on the factorio website or in the player-data.json): These are necessary if you wish to make the server public. Otherwise, they can be left empty.
** For security reasons it is recommended to use authentication token as this document is stored as plain text. Though it should be noted that an authentication token is a sensitive piece of information as well, and you are well-advised to keep it secret.
* Server Password
** Field name is game_password
* Whether to verify user identity
(There are additional values in v0.14 of factorio.)
=== Technical Implementation Details ===
Notes about some technical details surrounding multiplayer have been published by the development team in several Friday Facts blog posts:
* [http://www.factorio.com/blog/post/fff-76 Lock step architecture]
* [http://www.factorio.com/blog/post/fff-99 Client-server connections]
* [http://www.factorio.com/blog/post/fff-143 NAT punching, introduced in 0.13]
=== More Guides ===

* [http://youtube.com/watch?v=MqsqRWNsbPM How To set up a Factorio Multiplayer Server | Guide | Tutorial], by Teaspoon
* [https://forums.factorio.com/viewtopic.php?f=53&t=6720 Tips to connect in multiplayer], by Nondre
=== Miscellaneous Tips ===
* The key for [[Console|Console commands]] is also used initiate chat in multiplayer. To execute a command instead of chatting, you need to type ''/c'' before the command. Commands executed are ''visible to all players''. Additionally, the multiplayer game must have been started with commands allowable for commands to work.
* Set the player's color using the command
/c game.players["player_name"].color = {r=0.7, g=0.5, b=0.1, a=0.9}
r, g and b are for red, green and blue respectively (possible values are between 0 and 1, use the right-most column on http://prideout.net/archive/colors.php to convert colors to rgb numbers). a is alpha channel aka transparency of the color to the base texture.
== Joining a Multiplayer game ==
As of version 0.13, players no longer necessarily have to port-forward to play with others. Players may join each other through Steam, or by just the port-forwarded host.
Players wishing to join a game may do so in multiple ways:
* Joining by directly inputting a public IP and port into Factorio.
* Selecting the server from the active public server menu.
* Joining through Steam's services.
* Playing a local LAN game.
It is recommended that players use voice chat (TeamSpeak, Discord, Mumble) because you need to talk a lot to coordinate connections, building, handling attacks, etc. TeamSpeak servers are posted in the [https://forums.factorio.com/viewforum.php?f=53 multiplayer forum]. The public Discord of the Factorio community can be found [https://discord.gg/yGQWgy5 here].
=== Joining by IP ===
To join a multiplayer game by IP, you will need to know the public IP of a valid server. You can find this through social media, websites, or by word of mouth. After acquiring the IP and port, simply go to play -> Multiplayer -> Connect to server, and provide all the information it asks for.
If the server has been set up correctly to accept public connections, you should be able to join the game.
=== Joining via server list ===
Factorio's devs keep a list of all public servers that declare themselves to the service, allowing players to join directly through Factorio. Most of these servers will be password-requiring, but many completely public servers can be connected to. To join via server list, go to Play -> Multiplayer -> Browse public games. Provide your Factorio.com login if asked, and a list of public servers will appear. Simply select one.
=== Joining through Steam ===
Steam provides a "game invite" system, simply use that to join. You can find more info about how to use steam in it's documentation. ''This is the most recommended way for the average player to use multiplayer with their friends, as it allows Steam to handle everything''.
=== Joining a local LAN game ===
If you have some friends on the same internet connection as you (in the same building or network), you may play a LAN game. Simply go to Play -> Multiplayer -> Play on LAN.
=== Finding Other Players ===
* Use the [https://forums.factorio.com/viewforum.php?f=53 multiplayer board in the forum].
* Many players use other software like Evolve to meet other players. This also has the "advantage" of creating a virtual LAN among the players. See down under software.
* Some also use [https://forums.factorio.com/viewtopic.php?f=5&t=9136 Steam] to find other players.
* There is an external [http://serverlist.lgms.nl/ server browser] with various search options.
* Tell your friends to buy Factorio, then play with them!
=== Connecting to a Server Behind NAT ===
Factorio requires that the server (in client-server mode) have a publicly accessible IP address or that all players are on the same LAN. If you are behind NAT, you must set up port forwarding ([[Multiplayer#Playing_over_LAN_.2F_Internet|see above]] for port number) or use virtual LAN software such as Hamachi or Evolve.
Multiplayer games will be launched in client-server mode (also [http://www.factorio.com/blog/post/fff-99 multiplayer forwarding] mode). In this mode, all clients send their network traffic to the server and the server forwards the traffic to the other clients. The advantage of this is that it allows games where some players are inside a LAN and others are outside. The disadvantage may be slightly more lag as packets must travel an extra hop (through the server).

* [http://steamcommunity.com/sharedfiles/filedetails/?id=653628496 A guide for connecting with Hamachi]
== PvP ==
In PvP mode, players can be on different forces. Each force can have one (free-for-all) or more players (teams). Each force has its own independent research progression. Additionally, each force's [[Turret|turrets]] and [[Combat Robot Capsules|combat bots]] will attack other players as enemies, unless a cease fire is set. Note that, depending on the scenario, cease fires may be unidirectional — setting a cease fire with an opposing force does not guarantee a cease fire from them in return.
To start a PvP game, you can select the 'PvP' scenario from the 'Play' menu, or download a custom scenario which also supports PvP.
After downloading a PvP scenario, you need to move it to your application directory, and create the multiplayer game using the scenario.
# Download the scenario and place the scenario directory in the ''scenarios'' directory within your [[Application_directory#Directory_locations_by_OS_and_installation_method|user data directory]].
# Launch Factorio
# Click ''Play''
# Click ''Multiplayer''
# Click ''Scenario''
# Choose the PvP scenario you want and click ''Create''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game
=== Forces ===
Forces can be manually created via the console. This allows any map/scenario to be used for PvP. This may not be as convenient as a pre-made PvP scenario, as there will be no way for players to turn on/off cease fires other than through the console.
Each created force has its own research progression and different forces may attack each other.
The console commands for setting up and controlling forces are below:
<pre>
game.create_force("Name")
--Creates the force "Name"
game.players["Player_name"].force = game.forces["Name"]
--Sets this player to the new force
game.forces["Name"].set_cease_fire("Other_force_name", true)
--Sets the new force ceasefire to the "other force"
game.forces["Name"].set_spawn_position({x = 10, y = 20}, game.surfaces[1])
--Sets the spawn position of the force
game.print(#game.forces)
--Prints the number of forces
for name, force in pairs (game.forces) do
  game.print(name)
end
--Prints the name of all the forces
</pre>
The ability of players and entities belonging to one force to interact with structures belonging to another, non-friendly force is limited. However, some types of interactions are still possible:
;Manual pickup from belts
: Players can pick up items traveling along a transport belt that belongs to an opposing force. Note however that this can't be automated: Inserters will ''not'' take items from an opposing force's belts.
;Belt network connection
: Belts will connect to each other regardless of force membership, so it's possible to extend an opposing force's belt line, and items will flow to them. It is also possible to side-load into, and place items onto (with inserters) an opposing force's belt line.
;Fluid network connection
: Pipes (and storage tanks, and pumps, &c) will connect to each other regardless of force membership. For example, it's possible to pump fluids out of or into a storage tank belonging to an opposing force.
;Cable and wire connection
: Players can freely connect and disconnect [[Copper_cable|Copper cable]]s and [[Green_wire|Red/Green wire]]s from any entity that supports them, regardless of force membership. Electricity does not belong to a specific force, and it's possible to power structures with electricity from an opposing force's generators. Similarly, it's possible to read and write signals into a [[Circuit_network|Circuit network]] consisting mostly of an opposing force's devices.
== History ==
=== Narrative history ===
Because of the potentially immense amount of activity on a map, the game engine utilizes a [https://www.factorio.com/blog/post/fff-76 lock step architecture]. All instances of the game run full simulations of the entire world and only player actions are transferred across the network.
Multiplayer games were introduced to Factorio with version 0.11.0. The only connection method available was peer-to-peer mode which meant every player had to be able to directly communicate with every other player. In version 0.12.4, a client-server mode of communication was introduced in which the server (either a dedicated one or the player who hosted the game) relays messages to all peers. This means that direct connection between all players is no longer necessary. As of version 0.13, P2P connecting is completely removed.
As of version 0.12.0, the game features "latency hiding" mechanics where the game simulates some of the player's actions locally to make some common interactions (such as moving the player's character) more fluid. Latency hiding is enabled by default, but it can be enabled or disabled in Options → Other → Enable multiplayer latency hiding. Not every action is a part of latency hiding – most notably, car or train driving and shooting are not a part of it. It is recommended to keep this on, as many actions will be very stuttery on a low end internet connection.
