Witcher 3 Remastered Has Broken an Ambitious Mod Restoring Cut Plague Quest, But Upcoming Update Will Include “Something Extra” to Make It Work Again

Background: A Remastered Version Meets a Decade-Old Modding Project

The Witcher 3 Remastered launched on September 29, more than a decade after the original RPG first arrived. Because the remaster adjusted a long-running game, established mods faced an immediate compatibility question. The WAR Project, an ongoing effort to restore a plague-themed questline CD Projekt Red abandoned prior to release, is one of the mods affected.

Spoiler Warning: This article discusses an abandoned questline concept, not the completed main story or ending.

The WAR Project is not a simple cosmetic add-on. It aims to bring back cut story material, so it depends heavily on the game’s files, scripts, and mod tools. When a remaster revises those foundations, a mod may need a fresh compatibility pass before it can run.

Development: The June Demo and the September Roadmap

The modders released a demo version of the WAR Project in June. In the latest status update covered by this timeline, four of 12 planned quests were playable in that demo, and a further four were listed as being in active development.

Before the remaster arrived, the team had originally planned to push a slightly smaller update live midway through September. That plan shifted because the remaster introduced a very large number of changes to the game.

On September 21, key WAR Project developer MerseyRockoff replied in the mod’s Nexus comments with a roadmap. The team aimed to release a phase 1 update within a week of the Remaster launch. Phase 1 would include the quests already present in the demo, a lot of fixes, and English voice acting.

The same roadmap pointed to phase 2 roughly two months later. Phase 2 would add four new quests, two remade quests, and two mini quests. MerseyRockoff also said that once the mod was updated to Remastered specifications, it would only be available for that version of the game going forward.

Latest Progress: Day Before Launch Confirms the Gap

Late on September 28, WAR Project developer Ferroxius posted an announcement on the mod’s Discord server. The message clarified that the mod would not work out of the box on The Witcher 3 Remastered. The cause was the scale of the changes made to the game, not a small script conflict.

The team also revealed a longer testing history. Ferroxius said all of the modders had been in direct contact with CDPR and Yigsoft over several months, helping test Remastered and the mod.io integration before release. Because the project kept shifting during development, they could not guarantee WAR would be stable at launch. They added that they had time to become familiar with the new additions and improvements brought to the game and the modding kit, and they expected the fix to take a limited period.

The announcement did more than confirm a delay. It said the team would endeavour to get WAR working and updated for Remastered as soon as possible. It also promised something extra with that update while the modders continued to work on the next phase of content. Based on the September 21 roadmap, the extra element appears to be English voice acting for phase 1.

What This Means for Players and the Mod

For readers who use the WAR Project, the immediate effect is a short compatibility gap. The Remastered version is now live, but the mod cannot be relied on to run correctly without the upcoming update. The team’s message presents the gap as temporary, tied to the remaster’s structural changes, not to the project being abandoned.

The update also changes the mod’s version support path. Once WAR is rebuilt for The Witcher 3 Remastered, it will only be available for that version going forward. That means players who want the restored plague-themed questline will need to be on the Remastered build rather than an older setup.

There is a practical benefit too. A remastered baseline can give the restored questline access to improved systems, tools, and integration points. The modders highlighted that WAR could be played on an improved baseline after the update, and that they had been testing the game’s changes alongside CDPR and Yigsoft before release.

Current Stage

At the moment, The Witcher 3 Remastered is out, while the WAR Project is waiting for its first Remastered compatibility update. The team has confirmed four of 12 planned quests are playable in the June demo, with another four in active development. The next milestone is a phase 1 update targeted within a week of the September 29 launch, adding existing quests, fixes, and English voice acting. A later phase 2 is planned roughly two months after that, with four new quests, two remade quests, and two mini quests. The full WAR Project remains aimed at an expansion-sized release sometime in 2027, after the actor for new Vernon Roche lines was recast the previous month following a severe incident of gross misconduct.
