These are no ordinary soldiers. This is no ordinary war. Welcome to the Nano, where the battle is fought on the microscopic level and the battle is for sanity. Losing is not an option when a world of madness is at stake. BZRK takes place in a world where new technology is changing the face of warfare. Biots, which are microscopic weaponry controlled by a gamer, fight on the Nano level. They infiltrate peoples brains, re-wiring things, controlling people and changing memories. Unbeknownst to governments and the general public a battle is being waged between BZRK and The Armstrong Fancy Gifts Corporation. Two factions who have the technology and both think that they are playing on the side of good. It's time to pick a side - any side - because in this battle, who knows if there is a right and a wrong.
