My Strategy Guide found here...

Gonna go test it out. I can imagine a great future where clans/guilds and PvP are possible *wishfully thinking.

Also, think I should focus in eliminating one faction first?

How steep is the difficulty spike in campaign. As in threat levels. I might have missed it if u mentioned it in ur FAQ.

Edit: holy bazunga the fighter blanket strategy owned. Like flied on s__t. Made my game much easier.
