Reverse Shockwave Grenade

These powerful weapons are usually found in spherical or cylindrical form. The Reverse shockwave operates very much like it's namesake. Using the gravitational pull of it's immediate surroundings, it absorbs the gravitational energy into itself, acting as the epicenter. Once the require amount of energy is gathered it is then released as quickly as possible creating a powerful field of concussive energy. Most targets within it's blast radius, usually 50 meters for standard powered Rev Shock Grenades, are pulled into the epicenter, and violently blasted away resulting in gruesome injuries or even death.
