All signs point to PC.
Thanks to data miner BlackScout (via RockstarIntel), we now know of several snippets of code that refer to a now non-existent PC version of the game. Said snippets include phrases like, “PARAM_companionAutoConnectIpPC” and “CommandIsPcVersion(void) 000000000166A12C”.
Rockstar has yet to confirm a PC version of the game, but we’ve already seen hints at one. First, a Rockstar employee mentioned a PC release on his LinkedIn profile. Next, a European retailer listed a PC version of the game for sale next year.
We’ll keep you posted as we learn more.
For now, Red Dead Redemption 2 is available on Xbox One and PS4. We reviewed the game here and have a number of (spoiler-free) guides available for use here.
