The Grenade Launcher shoots exploding grenades which deal area damage. The amount of damage depends on the distance between the target and the center of the explosion. Grenades can be fired quickly and travel in an arc. Grenades can deal up to 6 points of damage each (with 6 being a direct hit), the most damage per shot in the game. You can hurt yourself with your own grenade if you get in the area of the explosion, although grenades only deal up to 3 points of damage to the player. It can be used to blast yourself high if used correctly on a wall or with a timed jump (although this will still damage you). Some modded servers remove the damage dealt to yourself.
