The rocket launcher is an extremely powerful weapon, capable of destroying almost anything capable of being damaged. The chief advantage of this weapon is its destructive power and area effect (with its blast being capable of inflicting heavy damage several meters away from the point of impact). Although its rockets self-destruct after traveling a certain distance, its range remains impressive. The weapon's disadvantages are its slow aiming, and its potential to seriously injure or kill the operator if a rocket detonates at close range. Its weight is also an issue — the protagonist will be slowed to a walking pace while the rocket launcher is equipped.

In the rest of the GTA III Era (GTA Vice City, GTA San Andreas & GTA Liberty City Stories) the rocket launcher resembles a Russian RPG-7 portable anti-tank rocket launcher.In GTA San Andreas,this is the perfect weapon to start a gang war as it instantly kills enemy gang members.

In the GTA IV era, the rocket launcher again resembles the Russian RPG-7 portable anti-tank missile launcher, however it is not fitted with the PGO-7 optical sight usually seen on the launchers.
The Rocket Launcher can be purchased at the back-alley gun shops for $15,000 and each rocket will cost $5,000.
