This is the most common weapon used by low - medium level players in multiplayer.
If you use it in Multiplayer, try shooting while tapping the aim button again and again and it will fire faster. Do not use this strategy if an enemy is circling around you or trying to move around, but only during desperate measures.
It is sometimes useless if your enemy has a high-damage, high-speed projectile weapon.
The shots, once hits something, emits electricity. The same goes for the Hellraisers.
