ZERO is a single-player hyper-violent first-person shooter that blends souls-like difficulty with a rogue-like structure. The game is designed around fast and unforgiving combat where both the player and enemies can die within seconds.
You play as Kyro, a merciless assassin cyborg and the failed experiment of the creators of the Slayers. Left without purpose, he now fights through hostile environments, relying only on his agility, speed, and weapons to survive.
Combat focuses primarily on melee encounters. While ranged weapons exist, ammunition is limited and forces you back to blades and fists. Every fight is intense and mobility is critical — dodging, dashing, and striking at the right moment is the difference between life and death.
Your enemies are the Slayers: combat cyborgs programmed for defense and extermination. Each type of Slayer brings its own threat, from dodging and strafing to heavy gunfire and close-range aggression. They are built to overwhelm, forcing you to adapt quickly.
The objectives push you into dangerous scenarios. In one mission, Kyro must clear a subway station of Slayers while neutralising explosives planted on the tracks. In another, he infiltrates a cargo shipment yard to destroy illegal containers before they are loaded onto a departing ship.
Zero is about high stakes, short runs, and brutal encounters. There is no health regeneration, and survival depends on agility, aggression, precision, and timing.
