Protocol: Zero-Day
About this game
Protocol: Zero-Day is a brutal and fast-paced Action-Roguelite set in a cyber-apocalyptic world. Wield your electric baton, master lightning-fast dashes, and survive endless hordes of corrupted anomalies. Navigate the shattered digital grid, upgrade your stats, and purge the system before you are overrun. Pure skill, zero compromises.
A catastrophic Zero-Day error has shattered the network's physics engine, leaving behind a surreal, low-poly wasteland. As a lone program equipped with experimental melee combat protocols, you must dive into the memory mazes, shatter the illusion, and purge the corrupted Entity. Reality has crashed. It's time to reboot it by force.
