Hi all!
There is an interesting mechanic we are working on now - Invisibility. Units can become completely unseen and as such won't be drawn for other players (AI included). You can imagine what tactical possibilities that new skill will open.
This feature also requires a substantial AI refactoring. CPU player will be able to sneak on player, position its units and execute coordinated attacks from all directions!
This feature is complex to implement but will fit very well in the two next games we're working on: AOF4 and [secret title here].
All of best,
Les & AOF Team
