A Grenade Launcher is a weapon that is used to fire grenades using airbursts. Grenade Launchers are used to launch grenades a lot further than a human being can. Also, unlike normal grenades, Grenade Launchers use special grenades that explode on impact instead of detonating after a certain amount of time. Reloading the launcher is very similar to loading a shotgun: you put the grenade into the launcher chamber and load it by using a pump below the barrel. Grenade Launchers are very effective when it comes to taking out multiple targets taking cover behind an obstacle.
