Randolph Safehouse

Randolph Safehouse is a Railroad radiant quest chain in Fallout 4.

Detailed walkthrough
Drummer Boy will approach the Sole Survivor with a mission. A safehouse believed to be long dead, Randolph Safehouse, suddenly initiates contact with Railroad HQ. Mister Tims, the leader of said safehouse, requests help in clearing out certain locations to advance the trafficking of synth fugitives out of the Commonwealth. Desdemona thinks the sudden resurgence of Randolph is more than a bit suspicious, but gives the go-ahead on the mission and warns the Survivor to watch out for danger. This will initiate a chain of six side-missions.

Each time, the Survivor is directed to a dead-drop, a marked mailbox, which will contain a Randolph station holotape. Listening to the holotape is optional, it will be Mister Tims asking for a certain location to be cleared. Head to the location provided and kill all hostiles. This will mostly include synths, but can also include raiders, Gunners, feral ghouls, or super mutants. After the threat is eliminated, return to Desdemona to receive a reward.

There are six missions in total, with the locations randomized. After finishing the sixth mission, Desdemona will reward the Survivor with a large amount of caps, and the Institute Killer weave, a unique mod that can be applied to any upgradable clothing item.

Mister Tims meets the Sole Survivor in person after Desdemona gives the all-clear for direct contact to resume. However, Randolph Safehouse has to be abandoned, and the cell that operated out of it begins the search for a new safehouse location.
