not really a gravity gun alltho it would be cool xD
the weapons would spin around player in circular motion (on a plane or something simple enought code vise) and do aoe damage depending of distance from the player so there wouldn't be physics involved. tho this might indeed need a way to turn collision of from those weapons.

path of exile very likely do this by texture around player and calculates just the distance for performance reasons.

on gravity gun: if there is or gonna be a way to get player/camera position and rotation, it would just need a way to move the item along specific trajectory. getting if it hits something after firing... assuming raytesting.

If we decide that local scripts on items should be able to perform any movement, then TES3MP would need to synchronize everything.
