8 hours, shooter death particles.
The flying shooter falls leaving a trail from its center fin. Upon landing it releases a splash of particles in a sphere unaffected by gravity which travel to the extents of the explosion sphere. This wave disappears at the same time that a burst of stationary particles is released at the surface of a sphere matching explosion range extents. This shell is maintained by a steady spawn of particles on the sphere edge, some of which are pulled into the center. Occasionally a larger particle is pulled into the center with a ribbon.
The particles change color when the shooter corpse is made friendly. The sphere extents and particle speeds are based off the actual explosion range of the object.
Shooter no longer has trouble finding its AI controller, being built or landing. The dead shooter no longer has trouble landing.
Solved some weird walker path finding to the center of the platform. Whenever a trackable object is spawned it shouts out to the game mode which has every walker evaluate whether it should be tracking something other than the player.
