Just a pointer for the newbies like me, The tec planet cannon thing is great for slaping around the pirates late game, once there deffences get to high to attack and keep you deff up. Just build 2 of the max tec cannon(can't remeber its name off hand) and give'em booth barrels. Also i have a question about it, will 2 shots destroy any planet or can shields save them from the 2shot ? . Also how effective it in multi player ?
