ZeniMax Online Studios has revealed substantial changes coming to The Elder Scrolls Online (ESO), marking one of the most significant transformations in the game’s history. The development team, led by Matt Firor, Rich Lambert, and Susan Kath, announced that ESO will abandon its traditional chapter-based release model in favor of a seasonal content approach.
After eight years of annual chapter releases that began with Morrowind in 2017, ESO will transition to phased seasonal updates starting in 2025. According to the developers, this change will free up resources to optimize core experiences such as beginner tutorials and graphic upgrades, while allowing the team to explore new gameplay ideas.

Players will access the year’s content through a new Content Pass priced at $49.99, which includes all story content, dungeons, and events. Unlike the current ESO Plus subscription, which grants free access to dungeons, the Content Pass will be required to experience story-driven content.
The first major update under this new model will be “Seasons of the Worm Cult,” a direct sequel to the original 2014 base game storyline. This narrative focuses on the resurgence of the Worm Cult under a new leader called Wormblood, who is harvesting souls for mysterious purposes.

Content will arrive in phases, with Part 1 launching in June 2025. This update will introduce western Solstice Island, a new region in southern Tamriel that features a blend of Elven and Argonian cultures with a tropical Caribbean atmosphere. The island’s main city, Sunport, is jointly ruled by exiled Elves and the emerging Argonian Tideborn tribe.
The June update will also include a new 12-player Trial called Ossein Cage, set in a demonic ruin in Coldharbor. A summer event called “Riding Wall” will follow, where players across all servers must collaborate to break through a giant wall made of “soul concrete” to unlock the eastern region of Solstice Island.
Part 2 of the Worm Cult storyline will release in the fourth quarter of 2025, opening the eastern section of Solstice Island and revealing the antagonist’s ultimate plans. The environment will notably shift from bright to dark, signaling a dramatic plot twist. Familiar NPCs from the base game will return, including the popular Khajiit spy Razum-dar and Skordo.

Perhaps the most game-changing addition is the new Subclass system, which allows players who have reached level 50 to unlock skill lines from other classes. According to developers, this system aims to solve “class rigidity” by offering over 3,000 possible build combinations while preserving players’ emotional investment in their characters.
Technical improvements are also on the horizon, particularly for PvP. The new Cyrodiil Champions mode will simplify skills in large-scale PvP environments, allowing for three times the number of players on each battlefield. The starting island will receive graphical upgrades, including reworked water, vegetation, and lighting effects, and a new tutorial system will offer personalized content recommendations based on a player’s time away from the game.

During the Q&A session, developers addressed several player concerns. They confirmed that players can activate two subclass skill lines while keeping at least one original class skill line, though class-specific gear sets will remain tied to the original class. They also clarified that players who miss the Riding Wall event can catch up through later quests but won’t experience the real-time wall-breaking event.
While ESO will continue to receive incremental technical upgrades such as DLSS support, the developers stated there are no plans for a major engine overhaul. They noted that while trailers often showcase epic battles, ESO’s soul lies in its community and social elements. Moreover, the global reveal of these changes occurs today, April 11, 2025, with Part 1 of Seasons of the Worm Cult launching in June, followed by the Riding Wall event in summer and the conclusion of the storyline in the fourth quarter of 2025.
