About Prototype

Step into the shoes of a powerful shape-shifter with a vendetta in an open-world environment that combines intense action with deep storytelling. As Alex Mercer, you navigate a sprawling New York City, harnessing a variety of deadly forms—claws, blades, and whips—to combat your enemies and uncover a conspiracy that has shaped your existence. The game features a unique locomotion system, allowing you to fluidly traverse the urban landscape with parkour-inspired agility, scaling buildings and leaping between structures effortlessly. Another intriguing aspect is the ability to consume others, taking on their forms and memories, which adds layers of strategy to combat and exploration. This game is a must-play for fans of action-packed narratives and those who love to experiment with dynamic gameplay mechanics.
