Alright, I'm looking forward to it. Brilliant work after all!

@Vosstach
Yeah, I believe there is still room for improvement in this scenario. Maybe I can improve the AI's missions which you have indicated in the future. Anyway, thank you for your comment!

Owe to AI's inefficiency it could have been a difficult scenario. PLA aircraft are numerous but lack of arrangement. After repelling the first wave of attack I no longer met any formidable offense came from PLAAF. Chinese submarines were anxious to expose themselves and posed no threat.
At last I managed to destroy 3 Air force Bridages and the entire Naval detachment in the lose of only one warship and no more than 30 aircraft, A very miserable outcome((

In editor, under sides set the awarenss level to blind, thats if they are basically just there to complicate targetting. They then won't detect anything and just wander about as plotted.

@Flanker

Oh, is there a way to disable detections of neutral sides? I Didn't know that. Could you teach me how to do that please?
Now, about the scoring, the main point of this scenario is to defend with minimum casualties. So, I think I'm not going to change that.

Tried this, managed a score of average at minus 50. Scoring is clever but not sure it quite works, i sank pretty much everything and shot down many, but in effect these don't count for you.
I think the air defences need to lose the group icon, they look better as individual radars, not a group.
Suspect the neutral sides need a look. The game ran very slowly for me so I suspect they are not blind and the game is computing lots of detections?
