Unfortunately, the Heavy Cannon suffers from a bug that causes the primary fire sound to play every now and then despite having sound mods, as such not every shot is replaced. Changed sounds include the primary fire, Precision Bolt (basic and mastered), and Micro Missiles (basic and Primary Charger-powered, the latter of which very subtly utilizes sounds from the 2016 Pistol). While this results in a slightly more obtrusive sound, it nonetheless feels like a beast to fire, making the Heavy Cannon feel like a true heavy assault weapon. The second sound pack utilizes sounds from both the cut Pistol and the 2016 Heavy Assault Rifle, resulting in a much sharper and mechanical sound akin to a belt-fed weapon like the Heavy Cannon as well as its predecessor. Changed sounds include the primary fire, Precision Bolt (basic and mastered), and Micro Missiles (basic and Primary Charger-powered). These sounds are much punchier and impactful, retaining the bass-y, booming effects often found in Eternal’s sound design (and as such not standing out too much, true to the original). The first sound pack utilizes sounds from the burst-fire Pistol, cut from Doom Eternal before release. These two sound packs seek to make the Heavy Cannon befitting of its name, sounding much more powerful and distinct while remaining true to the original weapon. The Heavy Cannon’s sounds, while inherently very good and befitting of Eternal’s sound design, often leave much to be desired and not living up to the weapon’s namesake.
