You will first be tasked with going up and around the mountain to destroy trucks blaring noise in the area. When you arrive, talk to Guy Marvel to begin the 'Quiet On The Set' side mission. They will often talk about the Radon Mine, and the Hollywood people there. You can also ask NPCs at the Hope County Jail, or talk to survivors with '!' notes above their heads. There is a mine entrance with a neon 'Omega' symbol outside. You can reach the Grimalkin Radon Mine by following the road east from Hope County Jail, then turn onto the dirt road leading up the mountain.

To unlock the secret Omega Armor outfit, go to the Grimalkin Radon Mine at the following location (in the Henbane River area in Faith's region). Open it, go down the ladder, and enter the room with the bunk bed to solve the Foxhole Prepper Stash and unlock the Militia outfit. Follow the short platforming through the building to reach a hatch in the floor. Kill the enemies, then enter the destroyed building through the window. It is heavily guarded, including a flame thrower guard. To find the Foxhole Prepper Stash, go to the Armstrong Residence in John's region at the following location. The Militia outfit can be found in the 'Foxhole Prepper Stash' quest. You have to collect it from the tunnel again. However, if you drop it, it cannot be bought from a vendor. It works just like the regular modern RPG in the game, and can be refilled with rockets around the map and from the shop. The classic RPG-7 is leaning against the blue rusted truck, in front of the destroyed tunnel. Go to the indicated location in the west of John's region to find the classic RPG-7, which cannot be bought in the shop. It is an optional quest and not part of the main story. You can do this quest at any point in the game, even after having completed the story. At the end of the questline, you will get the Magnapulse alien weapon (you can find and equip it in the special weapons tab at any gun store) and 'Science Fact' achievement. Always return to Larry after completing one of his quests. In total this questline consists of four quests: 'Free Larry', 'The Hero's Journey', 'Close Encounters', and 'Out Of This World'. Once Larry is free, he will give you some follow up quests. You can disable it by turning off the three nearby generators (marked on the map once you discover Larry). When you find Larry, he will be trapped behind an electric barrier. He is at the 'Parker Laboratories' fast travel point, just west of Fall's End (main town in John's region). It is given to you by an NPC called Larry, in John's region. To get the special Magnapulse alien weapon, you must complete an optional Aliens questline.
