All weapons require ammunition to fire, if you run out you cannot use a weapon of that ammo type until you acquire more. Ammo is divided up into four types, Rifle, Shell, Bullet, and Energy. Each weapon in the game requires one of the ammunition to operate.
Ammo can be found in open-able level objects, bought from the vendor, or found after killing a monster (needs to be noted that energy cannot be found this way and can only be obtained through the vendor, if you run out during a mission, have a backup weapon that uses another ammunition type).
