I've not tried it but it's on my list of things to check out. It's been a while since I played A3, given that I normally play co-op with my buddy. If anyone of you plays Deadside or Insurgency: Sandstorm, then send me a DM and I'll invite you to our private server for some co-op, bashing IA a bit in hardcore, full tactical mode with ISMC mod and custom maps.
