So it took several reloads from beginning of battle to change the RNG tide in my favor. Shame. It was only second time when this mod brings me on knees (and many more awaits, certainly), but unlike invisible Lotus assasins this time I feel just overwhelmed by AI himself, not a particular new mechanic.
Enemies advanced toward the craft very fast and agressive and smoke cover doesn't help too much! Then at first I just landed two smoke grenades at bottom of dragonfly ladder and place most units slightly behind it (standard approach of vanilla XCOM1) - when on its first turn enemy just begin shooting at them as there was no cover!
When on second attempt I try be more cautious and keep most of squad in dragonfly and added one more smoke inside it - then on its 2nd turn AI just precisely put a RPG rocket into cabin... XD
So in next few reloads I started to spam smoke grenades more and more and try to spread units, which somehow helped.
After all I managed to kill all enemies without loses (Morozova dies as well, because of her agressivness, see lowest "+" on screenshot), but feel myself moked by AI in field of smoke covering.
So I have some very newbish questions, please help!
1. Can OXCE provide enhanced vision to some uints? Is it "spotter: 1" param?
2. If so, can another (neighboring) AI units benefit from it?
3. How many smoke grenades required for maximizing covering effect? Is staking works if grenades explodes in same tile?
