The Red Dead series was never released for PC, not even the first game in the series, Red Dead Revolver. But that can change with Red Dead Redemption 2, which arrived in 2018 at the PS4 and Xbox One consoles.
The résumé of a former Rockstar Games employee mentioned that he worked on PC versions, Xbox One and PS4 from Red Dead Redemption 2. The discovery was made by the user “bongos_mongos” from Reddit, who shared his discovery in r / PC gaming.
The PC version of Red Dead Redemption 2 was mentioned in the curriculum of Nan Man, who worked as a physics programmer at Rockstar Games in Toronto from June 2010 until October 2016.
It is emphasized that for the moment the curriculum has already been changed to hide the mention of Red Dead Redemption 2, however, the screenshot below shows that the PC version of the game was previously mentioned.
With Grand Theft Auto V Rockstar Games also opted to launch first the version for the consoles and only later the version for PC.
