Submachine gun

The Submachine gun is an upgrade from the Pistol. It fires the same ammunition and deals the same damage as the pistol, but with a much higher rate of fire. This weapon can easily handle moderate waves of small biters, but destroying nests requires damage upgrades or the more expensive piercing round. Regular and aggressive use will devour the player's ammo supply, and the high cost of producing ammo against respawning biters can stifle early game production. Due to the aforementioned issues the submachine gun is best reserved for personal defense. Players wishing to take the fight to the biters should instead invest in the assault friendly Shotgun.
