Jagex Reveals RuneScape 4, New MMO Built on Unreal Engine

Jagex confirmed the development of RuneScape 4 at RuneFest 2026 this past weekend, unveiling a new massively multiplayer online (MMO) title that will utilize the Unreal Engine. The announcement marks a significant evolution for the long-running RuneScape franchise, promising a fresh experience built on modern technology.

The reveal came during Jagex's annual fan convention, where executives detailed plans for the future of their gaming universe. RuneScape 4 is described as a completely new MMO, distinct from the existing RuneScape and Old School RuneScape. While specific gameplay details remain scarce, the use of Unreal Engine suggests a leap in graphical fidelity and potentially new gameplay mechanics.

Expanding the RuneScape Universe

Beyond the highly anticipated RuneScape 4, Jagex also announced an animated series set within the RuneScape universe. In a surprising collaboration, the series will feature popular content creator MoistCr1TiKaL, also known aspenguinz0. This move indicates Jagex's strategy to broaden the appeal of its intellectual property beyond the core gaming audience.

Furthermore, Jagex provided updates for its existing titles. Old School RuneScape players can look forward to the addition of Menaphos, a long-requested city, alongside a raft of new quests and content. These updates aim to keep the veteran player base engaged while showcasing the continued support for the classic version of the game.

The announcement of RuneScape 4 arrives at a time when the MMO genre continues to evolve. With major players like Microsoft investing heavily in online gaming and new engines like Unreal Engine offering powerful development tools, Jagex is positioning itself to compete in a dynamic landscape. The transition to a new engine represents a substantial undertaking, but one that could redefine the RuneScape experience for both existing fans and newcomers.

RuneFest 2026 served as a crucial platform for Jagex to communicate its vision and roadmap directly to its community. The company's commitment to both new projects and the ongoing support of its established games highlights a multifaceted approach to sustained growth and player retention in the competitive online gaming market.
