The Dual Neutron Disruptor is a powerful rapid fire weapon. It is not used by any enemies, thus the player must search for one, often hidden in a secret area. Once obtained, it is usually the most preferred weapon.
This weapon is one of two being able to hit the ceiling mounted turrets, the other is the Rapid-Assault-Weapon.
The weapon this most closely resembles from Wolfenstine 3-D and its various mods/ports is the Chain Gun. Both consume ammunition reserves very quickly and provide heavy firepower vs bosses or large clusters of enemies.
