As part of the Eden Corporations never ending quest to defeat death, they developed the Legionnaire exosuit. Prior to their nanite technology, this was the only known way to extend life indefinately. The 'body' mimics a human skeleton and can be reskinned as required for different purposes, the skull contains a fully intact brain from a damaged Legionnaire and uses advanced neural technology to interface between the exosuit and the brain.

When the Eden Corporation stopped communicating with the rest of the Guild, these suits were among the first resistance to be encountered. Unlike the zombies, they are fully conscious and work with the intelligence and experience of their owner making them a daunting opponent. On the battlefield they fight without skins, forming a nightmarish host that rapidly overwhelms their foes.
