So frustrating.. that enemies only seem to ever attack my alies when they have no knowledge of my existence but as soon as one spots me they go "durp a durp ignore every one get cole!!" Im making a Mission were you have whats know as the " Vermaak D 6 " * defected six* who aid cole in battle and im introducing Specific task so and so must do while you wait... * like spot out package locations or enemies* and when battle starts .... there kicking but but taking no heat WTH!!
This should be a simple case of making the enemies neutral to Cole, instead of Hostile. If you want a mix of them attacking another group AND Cole, but mainly the other group, make them neutral to Cole, but have a logic modifier that makes them hostile to Cole if injured (make sure you make the 'trigger' hostile to Cole, and not the entire
group). This will result in the enemies predominantly attacking the other group, but gradually, one by one, they'll become hostile to Cole. It's a workaround but it should create the illusion you're looking for.
