Radmin VPN is a VLAN service that provides access to virtual LAN networks. (It is the same what Tunngle was and today used as an alternative.) By connecting to the same network, players, from all around the world, can play in local lan mode together, just like in online mode. Servers are available at all times to play on, with less players, but there is still daily activity. Below you can find instructions on how to join.
Before you start, be sure that the version of your game is 1.03. (If you have the Steam, Uplay or GOG version of Far Cry 2, your game is this version.) You can check this in the upper left corner of the main menu. If yours is an older one, you need to install patch 1.03, otherwise you won't be able to see any servers. (Click here to start downloading the patch if you need it.)
First, got to www.radmin-vpn.com, download the Radmin VPN client on the main page by clicking on the 'Free Download' button and install it.
Next, join a Far Cry 2 gaming network. You can bring the Radmin app up by clicking on its icon at the taskbar's notification area. Select 'Network', 'Join an Existing Network' and click on the 'Gaming Network' tab. Then type 'far cry 2' into the search box and double-click on the 'Far Cry 2 [English 2]' network.
If you've done the above, you're ready to join servers on the Radmin network. Start the game and log in with a multiplayer profile. (Create one if you haven't got one yet. Both, online and offline profiles will work.) Select the 'Lan' option and on the next screen 'Join matches', then on the following screen, after a few seconds, all the available servers will be listed. There is also a video guide below that shows the instructions, from downloading Radmin to joining a server in the game . If the match list remains empty for you (you can't see any servers) see the 'Troubleshooting' section below the video. If you need more help, join any of the recommended Discord servers, where you can talk to other players.
Note: the same servers are hosted on all the networks, and as players from different networks can play on the same servers together, joining more is not necessary and can only lead to lag issues. Since the 'Far Cry 2 [English 1]' network is already being recommended somewhere else, here the 'English 2' one is recommended to avoid reaching the limit of 150 clients per network. The only exception to this are hosts, who, on the other hand, must join both of the above to make sure their servers are visible to all the players.
If you're also playing online and you're using the FC2MPatcher, you need to make sure that it is installed with the Radmin VPN interface selected. This means starting the tool, selecting 'Radmin VPN' in the drop-down menu, clicking on 'Unistall patch' and on the 'Install patch' button. After this, the game will be able to see the Radmin networks and also work in online mode.
