'''Servers''' allow many people to play a single game over a network (Internet being the largest). The server list is available in the multiplayer menu. To fetch the most recent list of servers you will need to update the list from the [[Master server|Masterserver]]. 

== Server bandwith requirements ==
To run a high quality, non-laggy server, you must make sure that you are not exceeding your connection's bandwidth limits. Assaultcube does not need a lot of bandwidth compared to other multiplayer games. However, it still is absolutely required that you make sure that your internet connection has enough bandwidth to run a server of your desired size. This can be done by checking your current bandwidth on http://www.speedtest.net/ (measured in megabits per second) and comparing it to the following chart:

Any player will send up to 1000 bytes data plus 700 bytes protocol overhead to the server. The server will send the data of every player to all other players, so every additional player will increase the amount of data and the number of recipients. This means that the server uplink bandwidth increases with the square of the player number. A doubled number of players will quadruple your uplink bandwidth needs.

Bandwidth calculation formula:
* For n players, the average incoming (= downlink) bandwidth will be n * 1700 Bytes/second
* For n players, the average outgoing (= uplink) bandwidth will be n * ((n - 1) * 1000 + 700) Bytes/second

To maximize your server’s bandwidth and potential, it is suggested that you:
* Connect your computer to your router/modem via Ethernet
* Completely turn off all other applications (especially bandwidth-heavy ones)
* Disconnect all other systems from the internet

If you host your server at home, make sure that you don't mix up the uplink and downlink speed of your internet connection. Also, do not host an AC server if you are sharing an internet connection.

== Setting up your own server ==
{{Ambox notify| text= '''Please read the [http://assault.cubers.net/docs/server.html Server Documentation] before!''' The most common questions we've had regarding server setup will be answered here to supplement the basic documentation. }}

[[Server setup|Setting up]] a server may be useful if you want to play a private game with your friends but do not want others to join in, for example. If you plan on making a contribution to the public list of servers you should know something about [[Server security|security]]. In addition, you must [[Port forwarding|forward your ports]] correctly if you want your server to be visible on the Masterserver. 
If you only want to play on a LAN, then you don't need (or want) the Masterserver, so you'll want to '''deactivate''' any port forwarding you ''may'' have in place. Simply start the server and on the clients use the menu or console to '''lanconnect'''.

As soon as you have read all other server related documentation, be sure to have a look at [[Server hints 1.0.4|The Complete Idiot's Guide to AC Servers (1.0.4)]].
