The musket does not consume any type of ammunition and can be fired indefinitely. It deals slightly higher damage than the Deluxe Flintlock, possesses a higher range, and has the same accuracy as the Deluxe Flintlock. However, it doesn't have any other ability, unlike the Deluxe Flintlock's [Q] doing 1000 damage and heavy bleeding, and requires a longer time to reload than other guns. Bullet damage is: 600 for a body hit, 400 for a limb hit, and 800 for a headshot.
Unlike other guns which are kept at the player's waist, the musket is slung across the player's back. This is only visual, however.
