PATIENT ZERO: VIRUS SURVIVAL is a fast-paced survival roguelite and hardcore virus simulator where you play as the ultimate pathogen. Control a deadly infection, mutate your DNA, and conquer the host in this action-packed survival game.

🧬 PRIMORDIAL CHAOS: THE INFECTION STORY
Born in the darkest corners of a forgotten lab (Project EvoCell), you are the result of forbidden RNA experiments. Now, you are free to begin your infection game journey. To survive the harsh environment of the human body in this hardcore action roguelite, you must consume healthy cells and turn the host's energy into your own instruments of destruction.

Viral Nova: Wipe out entire armies of antibodies with powerful energy bursts.

Toxic Trail: Leave acidic puddles that melt enemy membranes in seconds.

RNA Spikes: Your long-range weapon. These sniper projectiles pierce through cells.

Vampirism: Consume enemies to instantly repair your damaged code.

Viral Spores: Create microscopic time bombs that orbit around you.
