Far Cry 5 - Science Fact Trophy Guide / Achievement Guide - Put aside skepticism and help Larry (Solo Campaign only) [Bronze]

To earn this trophy you must complete an optional Questline about Aliens. It is given to you by an NPC called Larry, in John's Region. He's at the fast travel point "Parker Laboratories" just west of Fall's End (the main town in John's region).

When you find Larry he is trapped behind an electric barrier. You can disable it by turning off the 3 nearby generators (they get marked on the map once you discover Larry). Once Larry is free he will give you some follow up quests.

In total this questline consists of 4 quests:
1) Free Larry
2) The Hero's Journey
3) Close Encounters
4) Out of this World

Always return to Larry after completing one of his quests. At the end of the questline you'll earn the "Science Fact" trophy / achievement.
You can do this at any point in the game, even after having finished the story. It is an optional quest and not part of the main story.
