The Grenade Launcher is a explosive weapon that shoots grenades creating a large blast radius that does very high damage. Players must carry grenades on their opposite hand to fire the Grenade Launcher.
A shot from a Grenade Launcher can lower any player's health by 50-75% of health when shot directly at. A second shot from it will kill the player instantly, same goes with any living things (including NPCs and spiders) shot at twice. Spider Egg's can be destroyed by Grenade Launchers, contrary to popular belief.
