In a world devastated by Umbrella Corporation’s bioweapons, Resident Evil 9 follows Leon S. Kennedy and Claire Redfield as they uncover a terrifying new threat. The remnants of Umbrella have developed a dangerous new T-virus strain, codenamed Thanatos, capable of regenerating its hosts and creating nearly indestructible mutants.

Leon responds to a distress call from a hidden research facility in the Himalayas, where survivors battle nightmarish bio-organic weapons (B.O.W.s). Meanwhile, Claire investigates mysterious disappearances linked to a secret Umbrella bunker in the Siberian tundra. As their missions intertwine, they discover Umbrella’s most horrifying creation yet—a Hive Mind Tyrant, a monstrous entity capable of telepathically controlling infected creatures.

Their journey leads them to Dr. Evelyn Graves, a rogue scientist who has fused herself with the Thanatos virus, becoming Nyx, an unstoppable bio-mutant with godlike abilities. With the virus on the brink of a global outbreak, Leon and Claire must destroy the Hive Mind Tyrant and stop Nyx before humanity faces total annihilation. Resident Evil 9 delivers intense survival horror, action-packed combat, and a gripping story that pushes the franchise to terrifying new heights.
