GoKawiilJagex confirms RuneScape 4 in early development, built in Unreal Engine
Jagex announced a new numbered RuneScape MMO, working title RS4, at RuneFest 2026—the first sequel since RuneScape 3 in 2013. The project started as a planned expansion to RuneScape: Dragonwilds, Jagex's Unreal Engine 5 survival game, but became a standalone title after playtesters asked for a traditional MMO set in the same world. Jagex released only a CGI teaser showing Ashenfall years after Dragonwilds, with no gameplay, platforms, engine version or release window confirmed.
