[Update #2]: It took a while for us to get the official announcement, but Returnal will be heading to PC in early 2023!
[Update]: The remastered Uncharted: Legacy of Thieves Collection is heading over to PC on October 19th.
Thanks to Sony recently boasting about how well their PC ports have done, as well as how much they have planned for the future, a fair few rumors started spreading about which games we might see make the transition onto PC next. While the truthfulness of many of these rumors is still in question, I'm happy to say that it looks quite likely that the bullet hell roguelike Returnal is indeed heading towards PC!
As noted on SteamDB, the freshly updated app named 'Oregon' sports a whole bunch of tags that very heavily point towards Returnal: third-person shooter, bullet hell, sci-fi, rogue-like, female protagonist, and the list goes on for a while. And just to really drive the point home, Oregon's update history also mentions Returnal's endless mode - Tower of Sisyphus.
So while no official announcement has been made just yet, I think it's safe to assume Returnal really is coming to PC. That said, I would advise against getting too excited just yet since we don't know how far along the PC port truly is, and as such when we can can expect to see Returnal actually arrive.
Once that changes I'll make sure to let you know. Until then, I'll leave you with the original launch trailer. Enjoy!
