Evolve has been shutdown (11/11/2018) so we're waiting for their new VPN (Bowstring) to test it.
Hamachi has also been filled so for the sake of new players and managing server, we move again.
For now we will play in Radmin.
1) Install Radmin VPN (http://www.radmin-vpn.com/).
Like Hamachi: change the metric settings of Adapter to 1.
2) Change your Radmin VPN Alias to FC2-Username:
In Radmin menu, click System and then Change Name.
Enter your FarCry2 Username (same as in Discord, no clantag needed) and press Enter. Done!
3) Then join the following Radmin room:
Network name: Far Cry 2 Community
Password: farcry2
