Copied (from myself) from a different post: An exotic heavy weapon that just looks like a metal ball, like as big as it can be to be one-hand-throwable. Heck maybe even like basketball size, carried in two hands, but thrown with one, kind of like dunking the relic in Kings fall start. you want it could have nifty computer effects on it, or better yet, it's like future vex tech that the Ishtar explorers found and somehow sent back NTtE style. So it looks all vexy. You could melee guys with it for free, but that would be no more powerful than a standard melee attack. The actual attack would involve hurling it at foes. Holding the trigger would cause it to have a sort of black hole effect, drawing enemies toward it, but slowly draining your heavy ammo. Releasing the trigger (or running out of ammo) would cause a sort of singularity collapse that does greater damage depending on how long the trigger was held and how close the targets were to the device, ranging from painful to catastrophic. I think for effect, it should fling bodies, enemies etc away pretty hard. Throwing without holding trigger would be like a slightly amped up grenade. In order to avoid something massively OP in the crucible, heavy drops would only give you enough to make one really good explosion, or like three smaller ones. But it would have upgrade nodes to allow for PvE fun. Tap trigger again to retrieve the weapon I'm thinking void. Sorry about the wall of text.
