B is for Blaster the hand gun of choice in the Deep Dark.
The blaster is a plasma based design effective against all targets, but even more so against Robots because of the ionized nature of the plasma (i.e. superheated gas with electromagnetic properties).
In plasma-based blasters, a high-energy gas moves from the ignition chamber into the receiving chamber where it is ejected by mico-magrail as a plasma bolt through the collimating components. This turned the mass of plasma gas and energy into a coherent energy bolt of plasma.
