RS4 Platforms
RS4 platforms have not been announced. Jagex listed platforms among the questions it says are too early to answer, so PC, console and mobile versions are all unconfirmed. Building the game in Unreal Engine does not by itself confirm any platform, and we will add each one only when Jagex does.
What Jagex said
"Which platforms? What accounts? Membership? Progression? Combat? Skills? When can you actually play it? But, the answer right now is that it's simply not the right time, or just too early, for us to say."
What it means
Platforms are explicitly on Jagex's list of questions it is not answering yet. Unreal Engine runs on many devices, but that alone confirms nothing about where RS4 will be released.
What to watch next
Platform news would normally arrive with a fuller reveal; Jagex points to 2027 for more details. We will mark each platform confirmed only when Jagex names it.
Is RS4 on PS5, Xbox or Steam?
Not announced. Jagex has not named PlayStation 5, Xbox, Steam, PC or mobile for RS4. Each platform will be marked confirmed here only when Jagex names it.
