You get the control panel for free, and we host the server 24 hours a day, seven days a week. Server rental will give you the best value for money.
You would also need to install MySQL and configure it.
However, on the downside, there is the initial setup of the Killing Floor 2 server which can take some time and expertise to get right, as well as updating it when an update comes out. You get root access to the machine so you can easily update the server and run it with a Windows batch file. With a dedicated server, you will get all of the resources focused on one or several servers so you can guarantee the best possible performance. This option has some great benefits and we do offer dedicated servers should you go for this option.
