This guy was a lifesaver for me, especially on Beachhead and Reactor.

buy one base upgrade all the way heavy supply pads double reactors heavy terets with

anti are upgrade and and billed an army of scorpion tanks with all upgrad and then go jack the scarab and keep doing the same thing to every base.

jack the locust and kill the base

build turrets and upgrade them to large turrets with anti air, put forge or a spartan in suply elevater.

build a army of hornets or tanks and go get a secound base while defending with a few hornets and the spartans and turrets

jack the scarab and kill everything 

hey ill help. add me.
