ArmA 3's Zeus DLC adds the curator module, a showcase mission, and several Zeus-based multiplayer scenarios. It is a free DLC that is available by default to all ArmA 3 owners and was released on April 10th, 2014.
It allows players to assume the position of "Zeus" in any scenario when the module is activated in that mission. While controlling this position, one can place objects, structures, and AI. Objectives can be created, and the setting (time of day, weather, etc.) can be modified on the go in real-time. Players can also "call" upon Zeus to aid them at the press of a button.
