Ballistic Heavy Weapons

Heavy Weapons deal physical damage. Heavy weapons use both explosive ammo and normal ammo which while easy to acquire is spent rapidly by the heavy weapon. Explosive Ammo on the other hand is much harder to find and more costly to buy from vendors. This means you will often end up using heavy weapons in addition to other weapon types in Starfield.

You can increase the damage that Heavy Weapons do by investing skill points into the following Combat Skills: Demolitions, Ballistics, Heavy Weapons Certification, Marksmanship, Rapid Reloading, Armor Penetration, Crippling and Sharpshooting.
