GTA 4 for GTA 3

Good model. In realism, there are special forces.

High quality helicopter to replace the police helicopter. Optionally, you can replace the escape.

Replaces The Escape. Where to look for or when it appears I do not know if can replace the Chopper (police Helicopter).
P.s. Fire at the helicopter from a rocket launcher would be fun!
P.s. the helicopter appears in the last mission.
