While the world ofFalloutis vastly different from the locations we see today in the real world, getting a hand on the scope of the show’s new map and names for certain towns caused more confusion than expected. In one of the TV show’s most significantchanges fromFallout’s games, animportant setting for the characters’ journeys in season 1 is Filly, a location absent from the original video games.
The majority ofFalloutseason 1 occurs either in the Vault-Tec vaults or around the devastated ruins of Los Angeles, with the “surface” often receiving new location names after being devastated in theGreat War of 2077. For instance, there’s the more general New California Republic, Shady Sands, Mojave Wasteland, New Vegas, and Filly. Whilethe new names are generally inspired by former cities or geographic landscape, Filly’s origins confused me until after watchingFalloutseason 1’s ending.

“Philly” Exists Separately In The Fallout World
Whenever I heardFallout’s main charactersmention Filly,I imagined the location was somehow linked to “Philly,”referring to the nickname for Philadelphia, Pennsylvania. I knew thatFalloutseason 1 was set in the Los Angeles area, whereas Philadelphia is in the Northeast, but I still believed the wasteland settlement’s name was inspired by the original city, using an incorrect spelling.
However, as I learned afterFalloutseason 1’s twist-filled finale,Filly’s name is actually derived from “landfill.”That detail is confirmed by Amazon Prime Video’s X-Ray trivia, and makes sense given the center of Filly inFallout’s TV show mapis a “giant pile of trash that is slowly sinking into the earth.”
While Filly is an original town for Prime Video’s TV adaptation, the franchise now has two prominent locations pronounced the exact same way. After watching season 1, I learned thatPhiladelphia does still exist inFallout’s video game universe– or, at least its wasteland remnants do – and, of course, is referred to almost exclusively as “Philly.”
Without subtitles,it’s going to get difficult to discern which “Filly” or “Philly” characters are talking about unless they give additional context. However, it seems unlikely thatWalton Goggins’ Cooper/The Ghouland Ella Purnell’s Lucy MacLean will make it that far east inFalloutseason 2 with their current destination being New Vegas, so the Filly/Philly confusion shouldn’t become a problem for some time.
I’m So Excited For Fallout Season 2 To Expand On The Show’s Wasteland Map
Fallout Season 2 Will Have A Larger Scope
Themap ofFallout’s post-apocalyptic American wasteland is one of the show’s most interesting elements, and being able to expand on that is a great advantage forFalloutseason 2 to have after a stellar inaugural season. In season 2, Cooper and Lucy will be heading to theiconicFalloutvideo game location New Vegas, built upon the ruins of Las Vegas, Nevada.
Falloutseason 2 is confirmed to premiere on Prime Video in December 2025.
To get from post-war Los Angeles to post-war Las Vegas, however, will take Cooper and Lucy across plenty of different locations and environments from what they faced in season 1’s arduous journey.They’ll spend a large portion of time in the Mojave Wasteland, exploring much of former Southern California and Nevada as they search forLucy’s father Hank MacLean in New Vegas.
WhileFalloutseason 1 did a fantastic job of exploring a post-apocalyptic Los Angeles,Falloutseason 2’s worldbuilding will occur on a much larger scaleas they leave the city. Not only will more locations from the video games inevitably appear on their journey, but, like with Filly,Falloutseason 2 also has the opportunity to introduce brand-new locations original to the show.
