Free Adytum from the Regulators

 is an unmarked quest in Fallout.

Walkthrough
This quest can be accomplished at any time. Just start shooting up Regulators in the streets! After all of them are dead, the town will be freed.

Get the Blades to help
If you got the weapons for the Blades, 5 heavily armed Blades will accompany you into the map. Each is wearing Combat Armor, two have AK-112 Assault Rifles, two have Wattz 2000 Laser Rifles, and one has a P94 Plasma Rifle. With their help, the Regulators don't stand a chance.
