This is a vary simple mod based on the institute Beacon. The reprogrammed Synths are loyal only to the player and are quite durable. 
There are 6 personalities with there own weapon sets, fighting styles and voices. They are nonessential, uncontrollable followers. You cant dismiss, interact or trade with them.

Sigma - automatic weapons

Assault - Melee weapons with extra HP and speed

Guts - Sniper Ranged

Prime - Heavy weapons small chance of explosives

Handy - Pistols

Proto - Shotguns

Beacons can be crafted at the chem station.



Bugs:
The usual follower bugs. They tend to get stuck in walls and are horrible at pathing in multi level areas and door blocking.

They disappear sometimes when you fast travel or enter/exit interiors. I don't know where they go.

They teleport 5 at a time. The more you use the more unstable the game gets. Using high spawn mods (Like I do) will cause the game to crash more often.
