However, after shooting “some stuff,” it “just disappeared”, and Rockstar never followed up with them on the same. That is, until now. Sort of. Former lead writer and Rockstar co-founder Dan Houser finally opened up on the DLC while speaking to Lex Fridman.

“The internet knows we made a DLC… single-player DLC for GTA 5 that never came out. It was one when you played as Trevor, but he was a secret agent. It was cute.”

However, much like the studio’s forays with cancelled PS3 spy fantasy Agent, “It never quite came together, and it was never finished. It was about half done when it got abandoned. But I think if that had come out, we probably wouldn’t have been able to make Red Dead Redemption 2. So, there are always compromises.”

While it never revisited the idea of releasing single-player DLC for the open-world hit, Houser still enjoys the model. “I like making the stories. For me, I love the model of Grand Theft Auto 4, where you had the extra stories coming afterwards, or Red Dead 1, when you had the zombie pack afterwards. I like just doing these extra things.

“So, I would personally like to have done more of that in that company. And with stuff we’re doing in the future, we’re going to try to come up with worlds where we can add more stories. I like single-player DLC. I just think the audience loves it, and it’s really fun to make.”

With Grand Theft Auto 6 next on Rockstar’s release schedule, launching on May 26th, 2026, for Xbox Series X/S and PS5, one has to wonder if it will have DLC. Rumors have claimed that the company wants to expand on the title with “regular” post-launch updates, but it’s unclear whether those are free or paid.

There’s also the matter of Grand Theft Auto Online and how it will work in the sequel. As always, stay tuned for more updates.

Datamining from last year’s leak of the game’s source code indicated that several DLC were in the works, including Agent Trevor. Actor Steve Ogg confirmed its existence in an April 2024 YouTube stream with Ned Luke (who voices Michael de Santa). Even more alleged details have emerged, courtesy of former senior camera artist and virtual cinematographer Joseph Rubino.

In an interview with SanInPlay (transcription via VGC), Rubino, who worked at Rockstar for six years, claims, “I was one of the main editors, camera artist and doing a lot of the second unit on-stage stuff. We split our teams into two, so I stayed on GTA Online and then this DLC, which Steven Ogg was a very important part of, and then some of the team overlapped and went to Red Dead Redemption 2 early on.”

The success of Grand Theft Auto Online ultimately led to the DLC’s cancellation. “When GTA Online came out, it was so much of a cash cow, and people were loving it so much that it was hard to argue that a standalone DLC would out-compete that. I think, looking back now, I would say that you could probably do both, but that was a business decision they made.”

Rubino confesses to being “a little upset” at this, and it was “a lot of reason for me being a little sour at that time, because I was like ‘yo, what the f*** guys, this s***’s awesome, let’s keep going, let’s finish this s***.” Agent Trevor was allegedly half-finished at the time, though, “A lot of that stuff did end up making it, I believe, into later iterations of GTA Online, I think. It’s not like they wasted it. It was really, really good.”

Rockstar North has added its fair share of story-focused content to GTA Online, including “The Contract.” It focuses on Franklin Clinton, one of the three protagonists, years after the campaign and features music by Dr. Dre.

The development team is currently focused on Grand Theft Auto 6, launching in Fall 2025 for PS5 and Xbox Series X/S. It’s rumored to receive substantial content additions post-launch, but nothing is officially confirmed. Stay tuned for updates in the meantime.
