Sub-Machine Gun

The Sub-Machine Gun is a burst fire weapon in Fallout: Brotherhood of Steel that can be dual-wielded.

Gameplay
A very good weapon until the end of Chapter 2, that is also obtainable early in the game. It does the same damage as a Home-Made Machine Gun, but the rate of fire of the Sub-Machine Gun is higher, giving the player the ability to do more damage per second.
