The Loose Cannon is a community-created primary weapon for the Demoman. It resembles a pirate-style cannon with a stock and a sight near the front of the barrel.The Loose Cannon fires explosive, glowing cannonballs that travel 20% faster than the Grenade Launcher's projectiles, however, due to the Loose Cannon shooting a different projectile there is no difference in speed. Cannonballs explode faster than grenades, only having a fuse of 1 second. Unlike other grenades, bombs from this weapon do not explode when hitting players, instead dealing damage and significant knockback on the target while continuing in the same path, potentially hitting multiple enemies until it explodes due to its fuse or bounces off a surface. On Tank Robots, however, the cannonballs work identically to the default launcher's projectiles. The explosion of the bomb works as normal and has the same property as normal grenades where they deal half damage if they hit a surface before exploding. Overall the impact of a bomb deals half of what a normal grenade deals, and the explosion is 40% less damaging than a normal grenade, but shares the same explosion radius.The Demoman can hold down the fire button to start the cannonball's fuse without shooting until the button is released, allowing control over how long it takes to explode once fired. As a reward for doing so perfectly, if a cannonball impacts an enemy and then explodes within half a second, the enemy takes mini-crit damage from the explosion and ignores explosive damage falloff (meaning the total damage is 131); other enemies hit by the explosion do not receive Mini-Crits, and are damaged as normal. This is known as a "Double-Donk" and produces a unique sound and "DONK 2x" effect on success. Holding a primed shot for too long automatically fires the shot, which explodes immediately and deals damage to the user. Over-shortening the fuse in this way can allow for a strong grenade jump known as a cannon jump.Both the impact and explosion of a cannonball are considered explosive damage.The Loose Cannon was contributed to the Steam Workshop.
