Red Dead Redemption 2 hasn't been announced for the PC yet, but it's hard to believe Rockstar isn't at least considering a PC version of its new western. Now we have further evidence of a possible PC version thanks to some buried code in the Red Dead Redemption 2 mobile companion app.
According to Rockstar Intel, the Red Dead Redemption 2 companion app for iOS and Android devices include code that references PCs and even VR. These include command lines like "companionAutoConnectIpPC," "PARAM_Oculus" and various other references to PC graphical settings not present on consoles.
Rockstar hasn't officially confirmed a PC version of Red Dead Redemption 2, but the fact that specific PC commands exist on the official companion app is strange. Even if it's just a PC version of the same app there's little reason to include code for the Oculus and robust graphical settings for an app that just serves as a usefull guides and map tool (is there?).
The likelier explanation is that Red Dead Redemption 2 will eventually find its way to PC just like Grand Theft Auto 5 which launched on PC months after consoles. But again, there's no confirmation that Red Dead Redemption 2 will come to PC.
As of right now though Red Dead Redemption 2 is only on PS4 and Xbox One with not even a mention of a PC version. We have a review of Red Dead Redemption 2 here, or a full Red Dead Redemption 2 guide for console players trying to tame Rockstar's wild west.
