Fallout 4 lands fully-voiced new quest expansion that players dub 'peak' and 'instant download'

PC players have a new quest to enjoy in Fallout 4 that’s already been dubbed “peak” and an “instant download”, although perhaps that comes as no surprise, as this mod expansion is the work of the Commonwealth Story Expansion Project team.

Better known as CSEP, the mod team has delivered hit after hit over the years, with ‘CSEP Presents - Under The Stars’ being the latest offering.

Halloween may be over for another year but the frights continue, because ‘Under The Stars’ is on the spookier side, set within a disturbing underground facility.

“The harsh radioactive winds of the glowing sea have uncovered a deep underground facility full of secrets and horrors,” teases the mod’s very brief synopsis.

The team has described the new underground facility where the mod expansion is set as “huge”, and it’s here that you’ll get to enjoy new puzzles as part of the original questline.

There are also new holotapes to find, a brand new outfit and helmet for your character, plus two new weapons to use.

CSEP Team

All holotapes are fully voiced, truly immersing you in the story that the ‘Under The Stars’ quest mod tells.

In order to start the mod, you’re going to want to find a bunker which is located “in the lower part of the glowing sea west of the Sentinel Site”, according to the mod’s creators.

The bunker should have its own map marker where it’ll be tagged as “Sunken Bunker”.

Given the track record of the CSEP team, it’s to be expected that the response to the mod has been nothing but positive.

“Instant download,” said NexusMods user IronMind76.

“It’s so peak,” added Bread4Life.

User Masari953 wrote, “I wanted to say thank you for yet another amazing mod. It was really good and integrates quite well with the game and lore of it. No issues were encountered during the whole quest; everything worked perfectly on my end. Thank you and keep up the good work. Endorsed.”

Xbox is full steam ahead on Fallout, with four game projects in the works

If you do enjoy what ‘Under The Stars’ has to offer, I can highly recommend CSEP’s other recent creation, ‘Detour ’, which introduces a brand new town, once again, complete with quests, weapons, and other new items.

Don’t forget that Fallout 4 boasts full mod support on consoles. Not every PC mod is available to PlayStation and Xbox users, but there’s certainly a wide array of offerings via Creations well worth browsing.

This all comes amid a Fallout drought, although at least we now know that several new projects are in the works.

Bethesda is beavering away on Fallout 5 with remasters of Fallout: New Vegas and Fallout 3 also on the way.

Obsidian Entertainment is also developing a Fallout entry following Xbox’s major restructuring, although no details have yet been provided on precisely what fans can expect.

The remasters will undoubtedly be the first projects to come to light, plus there’s season three of Prime Video’s Fallout to look forward to in the near future with a possible late 2027 return expected.
