As our sister site Tom's Hardware covered on Christmas Eve, the entire source code for "GTA 5" was dumped online, as if in protest of the sentence handed down to an 18-year-old boy who leaked footage of "GTA 6" last year [Despite being the source code for a game that is 10 years old, the leak will no doubt cause a major headache for Rockstar

However, the leak also gives us an idea of what might have happened if the online mode had not quickly become a huge cash cow for the company: according to Insider Gaming, the leak mentions over eight DLCs that ultimately never saw the light of day

These are reportedly the names of the content in question:

Unfortunately, we can only rely on the names to know how far along or how substantial any of these were For example, the "SP [Single Player?] Assassination Pack" may just be a bunch of weapon skins

But it's still fun to speculate The "Prologue" seems to be a bit of a storyline before the game begins, while "LibertyV" suggests a return to Liberty City

Furthermore, was "Agent Trevor" a new solo campaign in which Trevor flips and goes undercover with the FBI? Was the "Relationship Pack" bringing dating and relationships back to "GTA 5" as they were in "GTA 4"? Most intriguingly, is the "SP Manhunt Pack" related to Rockstar's 2003 epic adventure "Manhunt"?

We will probably never know for sure However, there are some clues as to why Rockstar did not produce any single-player DLC for "Red Dead Redemption" or "GTA 4" during the Xbox 360/PS3 era, despite having produced several different types of DLC for them

"In 'GTA 5,' the single-player game was absolutely huge and very, very complete," Rockstar design director Imran Sarwar told Game Informer in 2017, essentially "three games in one" was one"

He claimed that it was "one of a kind

Since "GTA 5" was released just a month before the PS4 and Xbox One came out, the next-gen version, which came out a year later, was developed at full speed, with improved graphics, increased traffic density, and a brand new first-person mode Subsequently, the online mode proved to be a huge success, and "Red Dead Redemption 2" needed more help

Hopefully things will change so that single-player DLC will once again be feasible in "GTA 6," which will be released in 2025
