Set up resources. Build 4-5 defense towers at entry to your base (left top)
Then get about 20-25 tanks before you attack. Keep building tanks.
Before you attack, wait for a mass attack of the enemy. If you survied it, enemy is weak for your counter attack. Send it to the 2 towers of the enemy. Destroy both and the forces waiting there. Have 5 tanks wait there and destroy with the rest all buildings to the north (not to north / right !).
After you now cleared NW, forget the tanks and get about 20 walkers. Send them NE and keep your forces near bottom hill. Destroy the HQ and all spacecraft/ITABS. Then head straight north. Kill rest of ITABS. Get some reinforcements before you attack the 3 last towers to the right. Then just destroy the rest.
Well done !
