From publisher blurb:
Be One With the Machine!
A spacefarer’s life is a difficult one, fraught with danger. She is surrounded by hazardous environments, encounters strange and hostile alien species, and must often make do with outdated, or even glitchy, equipment. If one wants to live long adventuring among the stars, it’s important to be the best that one can be. The Spacefarer’s Digest series contains new player options and content, from character themes and races, to archetypes, feats, spells, and more, allowing every traveler among the stars to reach their maximum potential.
This volume presents an alternative option for a mechanic’s AI, allowing them to create something that is neither a drone nor an exocortex, but somewhere in between. Sophisticated and powerful suits of armor powered by AI, exo-suits give engineers the best of both worlds.
