About Prototype

Prototype™ puts you in the role of Alex Mercer, a man who awakens in New York City with no memory but extraordinary shape‑shifting powers. The game blends fast combat, fluid movement, and a deep conspiracy narrative as you hunt the forces that created you.

Set in an open‑world version of New York, the experience emphasizes adaptable combat, parkour‑style traversal, and the ability to consume and impersonate any civilian. The story unfolds through Mercer's search for his origins and a forty‑year‑old conspiracy.

01 / THE GUIDE

Shape‑Shifting Combat

Mercer can reconfigure his body into a range of weapons—claws, blades, hammers, or whips—allowing you to match the form to each encounter. Defensive options include forming a shield or armor for protection.

Advanced sensory powers such as thermal vision and infected vision let you locate enemies, adding a tactical layer to the melee‑focused battles.

  • Swap forms to see which best counters a given enemy type.
  • Activate sensory powers before engaging to improve positional awareness.

02 / THE GUIDE

Locomotion & Agility

The game features over‑the‑top movement, letting Mercer bound from building to building, run up walls, and bounce off cars. This adaptive parkour lets you navigate New York’s open‑world freely.

Movement is fluid and seamless, encouraging rapid traversal and dynamic positioning during combat or exploration.

  • Use vertical surfaces to escape tight fights.
  • Combine parkour with combat forms for uninterrupted attacks.

03 / THE GUIDE

Disguising Abilities

Mercer can consume any civilian at any time, assuming their appearance, memories, and any special abilities they possess. This enables stealthy infiltration and surprise attacks.

The disguise system provides a way to blend into crowds or gain access to restricted areas without direct confrontation.

  • Observe civilian routines before consuming to maximize the benefit of their abilities.
  • Use disguises to bypass heavily guarded zones.

04 / THE GUIDE

Conspiracy‑Driven Storyline

You awaken with no memory, only mysterious powers and a link to a town in Idaho. The narrative follows Mercer's investigation into his origin and the larger conspiracy that spans forty years.

Story progression is tied to uncovering the true nature of your powers and confronting those responsible for creating you.

  • Pay attention to dialogue cues that reference the Idaho connection.
  • Track story milestones to understand the timeline of the conspiracy.

05 / THE GUIDE

Prototype™ is released for Windows and lists the Steam Family Sharing feature, allowing a shared library between accounts on the same platform.

The game does not list support for macOS or Linux, focusing its release on the Windows operating system.
