The Power Pulse legs are produced by Neuropa and emit a ring-like electro magnetic pulse. The pulse has a cylindrical damage area extending upwards above the ring, and will damage all enemy units (structures, vehicles, Combots, and aircraft) within the blast radius, but has no effect on friendly units.
The Power Pulse deals low energy damage, but does have an area of effect that could potentially hit multiple enemy units. It's only comparable to the Blast Pulse from Rimtech, which deals kinetic-based damage as opposed to energy.
