Prototype

Summary

In Prototype, players become Alex Mercer, free‑running across Manhattan, consuming targets to steal identities and memories, and unleashing evolving bio‑weapons to dismantle Blackwatch and infected hives while piecing together a conspiracy. Its power fantasy, parkour flow, and identity‑stealing stealth helped define a cult duology that later continued with Prototype 2’s new protagonist and shifting perspective on Mercer.
