"A heavy driver that fires a burst of mass driver rounds in a cone shaped pattern. Devastating to small, fast moving targets."
Shotgun Driver unlocks the Mass Shotgun for use in any large weapon mount. This is a powerful weapon that can force any foe with weak drives to stay at a respectful distance, or it can be used on fast moving ships to deliver devastating punches at close range. The node is a dead end, but still quite a useful one for the kinetic effect, even after the enemy begins deploying armor that eliminates its damage capabilities.

Shotgun Driver will cost as much as 75,000 or as little as 25,000 research points to unlock, depending on luck.
