Tunnel Snakes Rule! is a side quest in the Fallout 4 Creation Club content "Tunnel Snakes Rule!"


Listen to the faint radio signal to be directed to the Fens Way station. Navigate the area to a door to the subway maintenance access. Enter through a Novice locked door, and through one of two arched doors in the wall to find what appears to be an abandoned camp. Clear this section of the metro tube and continue back right to be ambushed by a feral ghoul who crawls out behind some scaffolding ramps and another feral who appears to be sleeping on a bed.

What remains of Wally Mack, who is now a glowing one, comes down from the top of the scaffolding ramps. once killed, Wally Mack drops Ultimatum, a unique classic 10mm pistol that does 50 radiation damage on top of having a unique model no other weapon or item uses.

5 Listen to the Faint Radio SignalI've picked up a faint radio signal. I should tune in and listen.
10 Locate Origin of Faint Radio SignalI've detected a faint radio signal transmitting eerie noises. I should try to find the origin of the broadcast.
20 Investigate the Radio RoomI discovered a band of feral ghouls that seem to have once been people living in the subway tunnels. I should look around for notes that might tell me more about who they were.
30 Find Wally MackThe band of ghouls were once a gang that called themselves the "Tunnel Snakes". It seems they all suffered from high levels of radiation from somewhere within the tunnels. Their former leader, Wally Mack, could still be alive. He might be able to provide some answers for what happened here.
40 Defeat Wally MackI found Wally Mack, but he has become a hideous Glowing One from incredible amounts of radiation.
50Quest finishedI defeated Wally Mack, and Boston is now free of what remained of the Tunnel Snakes.


  • PCPC When the Sole Survivor goes to Concord, one of several glitches can happen with both this quest and Out of Time active:
    • The quest may prohibit Codsworth from searching the neighborhood, with his last line of dialogue bugging out.[verification overdue]
    • The dialogue with Preston Garvey may bug out after the door inside the Museum is unlocked.[verification overdue]
    • Entering through the door to enter the roof may not be possible.[verification overdue]
    • When the Sole Survivor exits onto the roof with the power armor and minigun, Concord does not have any raiders or the deathclaw boss, making it impossible to proceed with the quest to help Garvey and his wards. [verification overdue]
    • The enemies in Concord are present, but after the Sole Survivor kills them, Preston Garvey and his wards do not complete their dialogue and do not go to Sanctuary.[verification overdue]
  • [platforms tag needed] The Faint radio signal may not appear, preventing the player from completing this quest without console commands. [verification overdue]
    • Using console command "Setstage xx000e6b 10" will allow you to bypass listening to the Faint Radio signal, and allow you to complete the quest normally afterwards.
  • [platforms tag needed] Tunnel Snakes Rule! may also interfere with other Creation Club mods, preventing them from being started until the quest has been completed. [verification overdue]
