Armored Core 3 Codes and Unlockables (PS2)

Armored Core 3 is a mecha video game in the Armored Core series. Set in a post-apocalyptic future, Armored Core 3 depicts a subterranean society called "Layered". Layered is ruled by an AI simply known as "The Controller" and it dictates nearly everything that goes on in this world. The two major corporations, Mirage and Crest Industries, vie for dominance and control over Layered's land and assets. All is not right with The Controller however and odd things are happening that might even go so far as to suggest that the logic system is failing...

Like Armored Core and Armored Core 2, you are given a trial mission to see if you are talented enough to join the mercenary group dubbed Global Cortex. New features within Armored Core 3 include consorts (additional allies that can be obtained to assist you in a mission), detachable weapons (thereby lessening your total weight and increasing speed), and a new Core classification; Exceed Orbit (EO) which sacrifices the power of Overboost and allows you to deploy a built-in, autonomous weapon on your Core.
