Insane difficulty is made for really experienced players. Because you are obviously not an experienced player you should try normal or easy difficulty.hogwartswarrior wrote: just added both and playing insane difficulty
Generally, it's not enough in Alpha 12 just to run north in the middle of the map with one combat group. You have to use two or three combat groups. I use one combat group with a python tracked sensor tank and 12 python half-tracked bombards to move north over the ground in the middle. In the second group are 16 python hover lancers attached to an experienced python hover commander. This group runs north at the western edge and moves into the middle northern base to take the factories out. Or you can use one hover bombard groups each in the west and the east and one group with tracked tanks in the middle. Or you find your own way.
A few general hints:
Don't use so many combat units. The experienced you gain is spread over too many units.
Use the strongest body you have. You used the Cobra body in your saved game. This body is too weak. If you think your units are too slow, use the half-tracked instead of the tracked propulsion.
Recycle all the units you don't need anymore.
Build more repair facilities. One repair facility like you used in your saved game is not enough. They have to be short behind your combat group. Facilities in the back that you don't need anymore can be recycled.
To build all these repair facilities use more trucks.
As soon as it's researched use only the Lancer in alpha mission. All other weapons are too weak. Especially the Machine Guns and Medium Cannons you have in your army.
If you need some inspiration read the walkthrough here in the campaign thread or watch some at youtube.
