First Response Mod for GTA IV on Xbox 360? Not Available

Not available on Xbox 360. First Response Mod is PC-only—it adds emergency vehicles, firefighter/paramedic/police roles.

Consoles lack native mod support due to closed systems.

Alternative

GTA V (Xbox 360/One/PC) – Robust police chases, diverse vehicles, deeper gameplay—no official first-responder mod but richer base experience.
