Your job is to safeguard company secrets, but when a black ops team breaks in and kills the very scientists you were hired to protect, everything you thought you knew about your job changes.
Badly wounded during the attack, you have no choice but to become mechanically augmented and you soon find yourself chasing down leads all over the world, never knowing who you can trust. At a time when scientific advancements are turning athletes, soldiers and spies into super enhanced beings, someone is working very hard to ensure mankind's evolution follows a particular path.

A divided near-future: discover a time of great technological advancement, but also a time of chaos and conspiracy.
