Jagex used RuneFest 2026 to unveil its fourth RuneScape MMO, a still-unnamed project running in Unreal Engine and set in Gielinor’s Sixth Age, beginning in the Ashenfall region first shown in Dragonwilds. The working title RS4 marks the studio’s first major new mainline entry in over a decade, positioned explicitly as an addition rather than a replacement for RuneScape, Old School RuneScape, and Dragonwilds, each of which retains its own team and roadmap. The announcement arrived alongside a concept teaser that offers atmosphere but no gameplay, confirming the title remains years from release while Jagex leans on community-driven development principles honed across the existing trilogy.

The move continues Jagex’s pattern of expanding the Gielinor universe through parallel experiences instead of successors. Dragonwilds itself grew from Unreal Engine tooling that later seeded RS4, turning what began as a planned expansion into a standalone MMO pitched for a new generation. An animated adaptation developed with MoistCr1TiKaL and Lyrical Media was also revealed, signaling the franchise’s reach beyond games. Community discussion on Reddit and X shows cautious interest tempered by the long timeline and the studio’s history of juggling multiple live titles simultaneously.

RuneFest itself drew over 6,000 attendees in Birmingham, underscoring sustained player engagement even as the company juggles four distinct RuneScape-branded experiences. Jagex has opened early registration for updates and stressed integrity, permanent progression, and community input as core pillars, promising more concrete details next year. The teaser trailer and official blog remain the primary public artifacts for now.
