Walrider
Through the darkened halls of Mount Massive Asylum, the frantic whispers of the insane speak of an invisible monster that tears men to messy pieces. The monster is a deity to some, a predator to others, and is recognized as the most dangerous thing in the asylum by all. Project Walrider was a program to control and weaponize nanomachine-swarms. Based off of old Nazi journals, the process called for a host to be near death and on the verge of madness, which allowed them to access a dream-like state necessary to control the nano-swarm. The poor patient named Billy Hope was the first host of the Walrider Program, and his nano-swarms decimated the asylum attempting to escape.
