I'm at the mission where the scarab is incomplete and you have to destroy it with ground forces. Every time i build a big army fully equipped with scorpions, cobras, etc... and try to kill the scarab, the scarab destroys my army and an attack on my base is made. And yes, i destroyed all the nodes. i have a feeling that the comp AI knows to attack my base when i attack the scarab but i cant defend it along with not being able to fend off the scarab due to its fast destruction on my unites. any idea how to get passed this *******? lol details would help. thanks.
