RuneScape 4 announced at RuneFest 2026: Jagex reveals new MMO in Unreal Engine

The game is being developed in Unreal Engine and is set in Gielinor, but a final title has not been confirmed.
Early reports say the project is still in early development, with no release window or platform list announced yet.

What happened

During RuneFest 2026, Jagex unveiled a new MMO in the RuneScape franchise. Several publications describe the project as RuneScape 4, or RS4, while also stressing that this is not yet the official final title. The announcement was tied to a broader franchise presentation at the event.

The first details indicate that the game is being built in Unreal Engine. Which version of the engine is being used has not been revealed. It is also clear that the project is still in an early stage of development, with no confirmed release date or platform list.

Based on the available descriptions, the new MMO is meant to be a modern version of Gielinor. That would make it a fourth RuneScape MMO in a franchise that already includes RuneScape 3 and Old School RuneScape, although it has not yet been confirmed how the new game will relate to those existing titles.

2026-10-03: Jagex announces a new RuneScape MMO at RuneFest 2026, tentatively called RS4.
2026: In early reporting, multiple outlets describe the project as the fourth RuneScape MMO.

Background

RuneScape has been around for more than 25 years and has seen several major variants over that time. RuneScape 2 was released in 2004, while Old School RuneScape arrived in 2013 based on an older 2007 version. As a result, the franchise has long consisted of a modern mainline alongside a classic branch.

According to the current information, the new MMO is a separate modern addition to that lineup. Jagex has not yet shared details about gameplay differences, platforms, or a release window. The name also remains open for now, since RS4 is being used as a working title in reporting rather than a final product name.

Several sources link the reveal to a franchise roadmap shown during RuneFest 2026. There, the game is described as a project for a new generation of players, but the available information remains limited to the initial announcement and does not yet include technical specifications, monetization details, or further product information.
