We have had an Exile server for a couple months now.
It is on CA3
It uses CUP and ACE3.
You can get everything on A3 Launcher or you can just use the Swifty Launcher. Swifty pulls the mods directly from our server so you get the exact version running on the server.
I have created a video on how to setup the launcher and add our Repo. Once everything is patched and updated, you can join the server straight from the launcher.
For some reason the Swifty Site is down so here is the launcher Download.Swifty Download
