The Alliance was the result of the combination of Mirage, Crest, and elements of Kisaragi in response to the wide-spread devastation caused by the Unmanned Suicide Weapons.


The Alliance consists of two sections: Alliance HQ, in essence the command of the super-corporation, and Alliance Tactical Unit, the military arm of the Alliance. Although HQ technically controls all aspects, the Tactical Unit is capable of ignoring its order. The formation of the Alliance proves to be the final straw for Jack-O, who forms Vertex in order to oppose them. As a result, the Alliance and Vertex are rapidly approaching an all-out war, which comes to a head in Armored Core: Last Raven.

Although Alliance presents itself as a unified group free of the earlier conflicts of the corporations, the fact is that some of the old divisions remain - in particular, a small group of ex-Kisaragi scientists continue to work on biological research that was officially banned by the Alliance, but is secretly sanctioned by the former Kisaragi executives working on the Alliance's board. Eventually, their work leads to the perfection of the Amidas.

Depending on the player's actions, the Alliance may win the war, lose the war, or be devastated alongside Vertex by the Pulverizers.
