Restoring The Witcher 3's Cut 'WAR' Questline via REDkit

For game developers, the cutting room floor is a familiar, painful space. We spend months, sometimes years, designing systems, writing dialogue, and building levels, only to watch them get pruned during the final stages of production. Pacing, performance, budget constraints, or shifting narrative goals often demand ruthless scope cuts. But what happens when the tools to salvage that cut content are handed back to the community?

Recently, the modding community around The Witcher 3: Wild Hunt announced a massive restoration initiative: The WAR Project. Led by a team of modders including Moonknight, Ferroxius, Crygreg, Glassfish, and MerseyRockoff, the project aims to rebuild and complete a massive, 10-hour questline that CD Projekt Red (CDPR) cut prior to the game’s release.

As a developer, this is an incredible case study in quest design, production pipeline management, and how official SDKs like CDPR’s REDkit can completely transform post-launch game lifecycles.

The Production Reality of Cut Content

The "WAR" questline—centered around the Catriona Plague—was an incredibly ambitious narrative arc designed for the Velen and Novigrad chapters of The Witcher 3. In the original 2014 development plans, Geralt was to collaborate with established characters like Vernon Roche, Ves, and Thaler to track down Hector Kraft-Ebbing, a Nilfgaardian medic involved with the plague. The arc also featured The Witcher 2 fan-favorites like Iorveth, early appearances of Gaunter O'Dimm, and expanded roles for characters like Vincent Meis.

From a production standpoint, cutting a 10-hour, 12-quest campaign is a monumental decision. Why did CDPR do it?

According to reports from sources like GamingBible, Rock Paper Shotgun, and PC Gamer, the questline was cut around 2014. At that stage of development, the team was facing the immense challenge of packing the Velen and Novigrad acts with enough narrative density while keeping the main questline focused. Introducing a 10-hour plague narrative would have disrupted the pacing of Geralt’s search for Ciri. Furthermore, managing the complex branching dialogue, trigger states, and scripting for over a dozen returning characters introduces high QA risk close to launch. When resources are tight, side campaigns of this magnitude are the first to go.

Re-Architecting with REDkit

What makes the restoration of the "WAR" questline possible today is CD Projekt Red’s release of the official REDkit modding tools in 2024, along with the release of original, raw development files. For years, modders had to rely on datamining and reverse-engineering proprietary formats. Now, they have direct access to the same authoring toolset that CDPR used to build the game.

Restoring cut content is not as simple as flipping a switch. The mod team is performing a complex engineering task:

• State Machine Reconstruction: Re-linking broken quest nodes, conditional flags, and dialogue triggers that were orphaned when CDPR stripped the files.
• Asset Alignment: Re-importing raw scene files, level geometries, and matching them with modern engine configurations.
• Dialogue & Voice Work: Merging original, unused voiced dialogue with newly structured scenes, and using advanced modding techniques to fill in any narrative gaps.
• Open-World Integration: Ensuring the restored quests do not conflict with the existing Velen and Novigrad world states, quest lines, or character paths.

In many ways, the mod team is acting as a distributed QA and systems engineering team, solving bugs that would have cost a studio millions of dollars to debug in 2015.

The Value of Open Developer Tooling

For studios, creating public-ready versions of internal tools requires a significant upfront investment. Internal editors are often unstable, complex, and rely on proprietary third-party licenses that cannot be legally distributed. However, as The Witcher 3 demonstrates, the long-term ROI of open developer tooling is unmatched.

By releasing REDkit, CDPR has effectively outsourced the expansion of their universe. Instead of paying developers to maintain a decade-old game, they have empowered a passionate community to keep the IP alive. A 10-hour fan-made expansion scheduled for a full release in 2027 keeps the franchise in the news, drives Steam sales, and builds goodwill ahead of the next major Witcher release.

For indie and AAA developers alike, building with a "mod-first" architecture in mind is a powerful strategy. When we build modular systems that can easily import custom levels, script files, and narrative trees, we prepare our games to live far beyond their official support cycles.
