The Noto said:The Silent Hill 2 remake is a timed exclusive. We'll get it eventually. If you don't have a PS5 then I'd just find another way to play the original SH2 either via fan remakes, the original Xbox/PS2 releases or the HD collection, which isn't the best option, but you still experience the story, which is what's important.
If you get the Xbox version, play it on an OG Xbox. It's real jank using the 360 backwards compatibility.
