Bethesda's upcoming Fallout 5 may be a long time away, but the Fallout franchise is as popular as ever. Thanks to the success of Amazon Prime Video's show, with its third season expected to arrive in 2027, even folks who haven't played the games are getting into the series. Of course, thanks to the longevity of games like Fallout 4 and Fallout 76, there are plenty of people still discovering the most recently-released entries in Bethesda's post-apocalyptic RPG franchise.
Considering how popular Fallout is, there's never been a better time to be a fan. From merch and mods to game reveals and show rumors, there always seems to be something going on in the world of Fallout. And now, thanks to a dedicated group of fans, anyone playing Fallout 4 can try "Under the Stars," a new mod that adds an impressive amount of content to a game that's eleven years old.
Available to download on NexusMods, the new "Under the Stars" mod, officially titled "CSEP Presents - Under The STARS - Dungeon and Quest Mod," is a new DLC expansion for Fallout 4. Created by the Commonwealth Story Expansion Project Team, "Under the Stars" will have players exploring a deep underground facility that's been uncovered by the glowing sea. The mod promises secrets and horrors that await, as well as a brand-new quest that will show up on players' maps as "Sunken Bunker." The full content listing is:
- A brand-new, huge underground facility
- New puzzles
- Brand-new quest
- New voiced holotapes to find
- Brand-new outfit and helmet
- Two brand-new unique weapons
The bunker is located in the lower part of the glowing sea, west of the Sentinel Site. This will start the new quest, sending players on a treacherous journey through the underground facility. The "Under the Stars" mod also promises new puzzles, new and voiced holotapes to find, a new outfit and helmet, and two brand-new unique weapons. A trailer for "Under the Stars" can be viewed below:
The "Under the Stars" mod released for Fallout 4 through NexusMods on November 1, 2026, but a new update arrived on November 3. At the time of this writing, it has just over 4,000 downloads and almost 200 endorsements on NexusMods. It's also worth noting that "CSEP Presents - Under The STARS - Dungeon and Quest Mod" is a lore-friendly mod, and it was also created without the use of AI.
CSEP, or The Commonwealth Story Expansion Project, is known for making many other quality mods for Fallout 4, including the recently-updated "Fallout 4: Detour," which added a new town and quest, and "Brothers in Arms: Return Of The Outcasts," a mini DLC-sized quest mod. The Commonwealth Story Expansion Project is also behind some smaller-scale mods, including "Pete the Friendly Phantom," which adds a fun Halloween-themed companion quest to Bethesda's open-world RPG.
If you're feeling a bit burned out by Fallout 4, and feel you've done just about everything there is to do, then mods can be a great way to keep the game interesting. Mods like "Under the Stars" are especially great, since they add in numerous bits of new content. The expansion is available to download from NexusMods now, and Fallout fans should definitely consider checking it out.
