Isotope Professional Killstreak Bonzo Gnawed Grenade Launcher

The Grenade Launcher is the default primary weapon for the Demoman. It is a stylized revolving, break-action grenade launcher with adjustable sights and a wooden stock and foregrip.

The Grenade Launcher fires grenade projectiles (called Grenades, also commonly known as Pills and Pipes) with a team-colored glow that travel at approximately 1216 Hammer units per second. Grenades bounce off of surfaces and are subject to gravity. They can be bounced around corners or rolled down slopes to attack enemies without needing line of sight.

The Grenade Launcher’s projectiles detonate either on direct contact with enemies or enemy buildings, or when their fuse expires after approximately 2.3 seconds. However, after hitting any surface, grenades no longer explode on contact with enemies or buildings. Unlike most projectiles, grenades are not affected by damage falloff; as such, direct hits always deal 100 damage to their target at any range.

Grenades can also be used for a makeshift explosive jump, similarly to the Soldier’s Rocket Launcher, albeit with less control due to grenades not exploding instantly on impact with floors or walls.
