First 3 way battle with the new 6th edition rules

Well this was our first 3 way battle with the 6th edition rules and I must say I whooped!!! We had a 2000pt limit it was a fight to the death and in our 3 way games anyone can attack anyone we just roll off to see who goes first.....
The battle was between necrons (me), dark eldar and his much loved lance weapons (Andy) and space marines (lord Andrew Carr) not to go to much into it. My tachyon arrow was successful strength 10 ap1 took out the dark elders heaviest vehicles primed with hordes of lance weapons, gone in the first turn. My scarab swarm were a right nuisance to the dark elders vehicles. The c'tan shard cost me a staggering 215 points roughly but dominated. I finished the game with about 20 necron warriors left (there re animation rolls were spot on today, saved at least 12 with an orb lord) a c'tan shard, 8 immortals, an overlord, 3 lords and a doomsday ark. I have learnt flyers are a pain to kill especially when you don't know which units have the sky strike special rule. Gauss weapons against vehicles are good. Overwatch is a great edition to the game as well. So all in all. I WON!!

+ dont mind the paint job on my necrons. They a lot of the models were borrowed from my company as my necrons have been away getting pro painted for 6 months now. Many emails later and they have still not turned up, i am starting to worry :/
