This mod adds a weapon known as the "Personal Institute Relay", which can be found in the Institute's Advanced System wing.  Using this weapon
you'll be able to have your own personal relay that will allow you to
travel anywhere. Point, click, disappear, reappear. In short, it's a gun
that allows you to teleport to the location you shoot.

The following video will showcase the mod and what it can do.



Location of gun:



As of Version 3, a safe containing the relay can be found in both QASmoke as well as the exterior of Vault 111. This should make obtaining
the relay easier for those with a save in which the institute was
destroyed.

As of Version 4, there is now a new institute grenade weapon that teleports the victim high into the air and lets them fall to their death. This weapon is found in each of the chests in which the gun is found as well as being sold from the Institute's synth vendor when you first walk in to the Institute.

Currently it is using the alien blaster as the model, but this may
change in the future. This is stage one of the mod, and there will be
updates and improvements later. Hopefully we'll be able to cut back on
the load time and increase the distance you can teleport. However the
further away you teleport, the longer it is going to take to load it.
