Grenade Launcher (Classic)
From Team Fortress Wiki
The Grenade Launcher is a weapon in the classic Team Fortress games and is only usable by the Demoman. It fires grenades that either explode on impact or explode approximately three seconds after being fired. The projectiles appear to be blue (red in Quake Team Fortress) regardless of the player's team.
It shares a magazine with the Pipebomb Launcher.
The reloading time is about 3.5 seconds for all six grenades
100 average damage if Direct Hit. Damage decreases as the enemy is further away from the explosion.
