Yes you are right with objective and talking . I'm still learning how to use them in editor. You are right with unlimited spawn at the base. I need to decide if i want to limit spawns number or to put a bigger delay command (now it's only 60s).
To open other ways throught the base i put a green berret squad which arrives when you need it, they are full of c4 and dynamite
.
For the map you are right ,but now i think it's too late. I decided to use this map before your mission exit. I can change it a bit but not the main features . (The small base, the bridge, the village).
The pointers were my intention. They blink until guns are crewed, so you know when AA are disabled. Tnx for your work !
