In Arvale Protocol, the sprawling metropolis of Arvale City is home to 8.5 billion people – the last bastion of humanity, sealed off from the outside world by massive protective walls. Every citizen is implanted at birth with a device known as a B.D., a brain chip developed by the powerful mega-corporation A.V.A. Marketed as revolutionary supercomputers for the mind, these chips also serve a more sinister purpose: constant surveillance and control.
You play as Zeno, a man who wakes up in an underground facility after a deal goes wrong. Above ground, chaos reigns – a military-grade virus has infected the B.D. System, transforming the city’s population into sex-driven maniacs. Team up with three unique allies and begin your journey to uncover the truth behind the virus, the B.D. System, and the powerful factions pulling the strings from the shadows.
