Description
“The Enceladeum is—er, was—the Garlean Empire's greatest magitek manufactory. Many an innovation in engineering technology developed within its intimidating halls.
Most recently, its engineers were focused on the development of humanoid machina. One of their latest models, dubbed "Armstrong," was designed with a self-regulation system never before seen in the Empire's machina.
Unlike your standard machina, which require mission parameters and combat protocolos be programmed in advance, Armstrong is highly autonomous—and indeed has been described as having "a mind of its own." If it sights allied troops in danger, for example, it will rush to support them.
With Garlemald in its current state, however, who knows what it's getting up to? The Faculty of Engineering certainly doesn't, but is nonetheless determined to find out what makes Armstrong tick...which is, of course, where you come in.— Lubdahrm, Old Sharlayan Aetheryte Plaza, Old Sharlayan
Trivia
Armstrong shares notable similarities with The Cyberdemon, the most notorious enemy from the DOOM franchise. The obvious traits being a cannon-arm, large bull horns, and a maliciously augmented body. A further possible nod to DOOM's demonic theme: A player must be "sacrificed" to spawn him; in the guise of a soldier no-less (yet another possible reference to DOOM's Marine protagonist.) Another possibility is that Armstrong is simply lured-out by an apparently fallen comrade.
