"The Heavy Laser Turret"

Basically the Mother droid's Rectangular gun but yours.

Pros:

 * High damage per shot.
 * Large amount of laser bolts fired per burst.
 * Gun automatically tracks enemy and leads shots.

Cons:

 * Low BpM (Bursts per minute).
 * 1 hand will be occupied due to the need of supplying energy to the Tesla Coil, reducing both defense and offense capabilities.
