all u have to do is wat u would expect to do....get many goliaths and tanks to knock out the air easily with the goliaths and to knock out ground easily with the tanks. REMEMBER: u must upgrade all the way for all of them!!!The tanks also get your opponents D completely wiped. And if you notice that your opponent is attcken u with a lot of air....get valkyries too and try to upgrade them. i hope this works for u. it works great for me!!

CreepColony's Opinion: And remember to (obviously) siege your tanks.
