-set in New York
-city got levelled to the ground (except for Statue of Liberty, Empire State Building, Central Park, Madison Square and other famous landmarks, because Pre-war companies and Enclave knew that war was coming, so they asked Vault- Tec to store them underground for some wacky experiment. When Vault Dwellers exited Vault 123 they took those landmarks with them to the surface)
-game is set 2000 years after war
-Mojave aliens wiped out everything 3 years ago
-there are 3 factions: BOS, Aliens and Settlers
-aliens experiment on people and create Ghouls, Raiders and even Super Mutants from FEV sample that government gave to local kindergarten

-you can buy Community DLC that gives you Top 10 mods from Creation Club
-everyone uses bottlecaps because reasons
-main quest resolves around you finding your father`s son- YOU (10/10 IGN heartbreaking journey centered around finding yourself in cruel post-post-post- apocalypse world)
-you can buy Cabot DLC, where you help Jack Cabot travel in time to kill Mojave Aliens ancestors (West Coast protagonists)
-infinite endings (actually only one slide, but each player`s world is different than others- you built here bed and your friend built here cupboard!)
