The Grenade Launcher is a weapon that appears in Grand Theft Auto IV's episodes, The Lost and Damned and The Ballad of Gay Tony. The weapon is based on the HK69A1 grenade launcher. The grenade launcher fires 40 mm grenades greater distances than a person throwing a hand grenade and is about as effective as a pipe bomb. It is best for removing cover, such as a car, however, the grenade does not land in a particular spot, making it less accurate. The grenade detonates on a seven second fuse. Grenades can be fired at and bounced off walls to reach tricky targets. When engaging long range targets, the player must arc the shot (aim higher than the target) in order to compensate for gravity. Although the grenade launcher is ill-suited for aerial targets, the player can carry more rounds than the RPG allows. In the Ballad of Gay Tony, it features an interesting improvement in which the grenade explodes on impact if it hits a vehicle or person. Also, the time it takes for the grenade to explode has been shortened to about four seconds.
The grenade launcher is only available from either Terry Thorpe in The Lost and Damned or Armando Torres in The Ballad of Gay Tony. In The Lost and Damned, the weapon spawns at the Lost MC Clubhouse and Brian Jeremy's Safehouse after completing 50 Gang Wars.
- It was originally going to make an appearance in Grand Theft Auto: Vice City but was taken out without any explanation, perhaps because grenades work the same way, and the launcher was just an aimed version. Its model (grenlanc.dff) and its textures (grenlanc.txd), still remain on the PS2 disc. These files were removed from all other ports of the game.
