The Plasma Inductor is a larger looking gun design than the other two weapons in the game. (The player does not see the weapon during game play per se, only the change of color).
The Plasma Inductor launches a concentration of crackling blue plasma that can vaporize small targets with a single hit. When striking a target the ball will explode, with devastating results.
Kinetic force will supercharge the plasma with more energy, causing it to inflict greater damage and a bigger blast when exploding. In order to do this simply bounce your shot off a wall or other inert object - when it hits, it will do so with more power.
