The Controller was created for the purpose of maintaining and commanding society, assigning roles to citizens, creating infrastructure, and manipulating the corporations. Despite its advanced nature, the AI is flawed, and degrades with time, thus setting into motion the events of Armored Core 3, where it systematically destroys the Layered infrastructure and support systems. It is speculated that this function was included in the AI on purpose, and that the builders of the AI assumed that by the time the Controller began malfunctioning and losing effectiveness, the scars of the previous war would have healed enough for the citizens of Layered to leave their sheltered lives and return to the surface. This is reinforced by the Controller's final directive.
Throughout Armored Core 3, The Controller has access to a variety of advanced weapons and technology.
MTs and other units
The Controller also appears to have many other units at its disposal, including remote-controlled versions of most MTs used by the corporations, as well as two custom units: a massive MT and another massive submersible weapon.
The Controller is destroyed at the end of Armored Core 3, starting an emergency program that causes massive blast doors to open, allowing access the surface world and the discovery of a new threat: the Silent Line.
- Based on what it says at the end of Master of the Arena, the Controller is very similar in function to Hustler One. However the Hustler One AI battles the player with an custom AC much more like IBIS than anything else.
- The Japanese version of Armored Core 3 has The Controller known as Dove. Interestingly enough, the Controller emblem has the words "Dove" on the bottom of the form. This goes along with the avian naming scheme of the AI in charge of the second Layered in Silent Line, IBIS.
