Thanks, glad to read something interesting after a while.
The "Fire Turret Exploit" is so cool. I've never thought of doing that :)
I find the "Military Fortress" pretty difficult at the beginning and I'm still having issues trying to destroy the Satellite Uplink. If you have any tactics for this part I would be more than happy to read them.
As soon as I get a triple plasma cannon knight, then with some luck I can shred enemy to pieces using this guy alone ^^
I also find "Take the Pass" and "Behind Enemy Lines" to be the best missions but I don't agree in regards to "Disable Relay Station Force Shield". This mission is different, challanging and you can't really use your 1st person advantage with wasps and on such small ground area.
It's almost always a graphics driver problem. Try http://wiredforwar.org/topic/167/announcing-community-patch-1-5-godsend or Voodoo patch (search the forums).
