In this mission you start to see combat, how you set up your base is on of the most important things in this mission as well as the ones that follow.
How did you set up your base and how long did it take you to accomplish the mission this way?
I located up my base in the most defensive position in the top left corner where there is only one way to attack at it. then I built 2 power generators RIGHT in front of it (like a wall, so the opponent will have to go through them first before they attack you main base HQ. this gives you time to build troops, ect. to defend yourself) Then I build the rest of my buildings in this "Row" manner only leaving one space in-between the buildings.
Also how many troops did it take you to beat this mission?
