I got buttraped by Tau in SS campaign 2 weeks ago. Haven't touched the game since them. I really really hate those blue assholes.
hehe, in the SS campaign it's a good idea to attack and destroy Tau first before they rise in power + when you conquer their teritory you will be able to use this big, bad ass cannon of theirs, it lowers the defense of every teritory you attack.
The funniest thing is that they were the second faction I attacked... I fought at their moon, and took it (after a 2 hour battle and with my forehead sweating). Then they only had 2 territories left. I thought they were going to be easier since I took their main territory... right? Well, no.
