Missions on the Dead Zone map
I have played this game mod as far as the map called Dead Zone which is a wasteland. The sky and atmosphere are green. When I started playing the game on the map, there were no notifications for me to do anything and no areas to capture. And to make matters worse, I couldn't use the radio. As for the enemies that invaded, most of them were Paradeus who attacked endlessly.
In summary, what exactly do the missions in this Dead Zone map require me to do in order to pass?
