You just put the small file to your SteamApps\common\Act of Aggression\Data\ACTOFRUSE\PC\260000304 and everything should be fine.
The objective was to have a better opposition so :
- the AI now can target all buildings on the map with their super weapons (not only the HQ...) so the antisuperweapon are criticals
- the AI moves faster from one tier to another - all levels modified
- the AI builds more superweapons and anti superweapons so it is not the better way to stay in the base and waiting for a peace time...
- the first bonus of income for hard and very hard levels have been removed
- the constant bonus over the time has been increased - no more sleeping AI... and more strategies from the AI that we never see since she doesn't have the resources to build and show...
The result is an improved opposition, which can be defeated of course if you can survive...
In 1vs1 it took me an hour on very hard with exchanges of superweapons, artillery strikes, battlegroups and well defended base with US against Cartel in order to get the victory for example.
I'm really curious to read your feedbacks if someone has time to test this small modification.
More interesting than the common AI, too easy, too difficult ?
Enjoy !
