Prototype™

Prototype™

Prototype™ centers on solo action: Alex Mercer reshapes his arms into weapons and parkours through New York. That makes it a better fit for someone drawn to direct, mobile combat than someone planning a co-op session. Use $19.99 at Steam as the current price point for this purchase decision. At $19.99 from Steam, you can weigh the offer against the announced Steam sale window Dec 17, 2026 – Jan 4, 2027; participation or a discount is not guaranteed.

Released June 12, 2009.
