Many new Modules have been added to Arma 3, all of which are fantastic. But many have been taken away. Specifically the Ambient Combat module. The civilian module was replaced by the "Sites" module which has since disappeared for a civilian settlement. An Ambient Combat or civilian module would be an excellent addition to the game. In the last mission of Arma 3 (if you chose to follow Miller's commands) you end up running through Altis with many different enemies near the area with friendlies around as well. A module that can replicate that mission in the editor would be fantastic.
