MT Framework: Capcom’s Engine Before RE Engine — and the Games It Still Ships

Capcom built MT Framework because it was tired of every internal team maintaining its own tools. It began in September 2004 as one programmer’s project based on the Onimusha 3 engine, shipped with Dead Rising and Lost Planet in 2006, and went on to power Devil May Cry 4, Resident Evil 5 and 6, Dragon’s Dogma and Monster Hunter: World.

It has since been replaced. RE Engine — which Capcom built on MT Framework 2.9 — is now, in the company’s own words, the engine it uses “to create all of our titles.” But MT Framework has an unusually long tail: it was still shipping games in 2025, nineteen years after Dead Rising. This page covers what MT Framework was, every version and what ran on it, what replaced it, and the answer to the question in the search box — no, you cannot download it.

What Is MT Framework?

MT Framework is Capcom’s proprietary in-house game engine, written in C++ and developed from September 2004. “MT” is documented as standing for three things at once — Multi-Thread, Meta Tools and Multi-Target. It debuted with Dead Rising and Lost Planet: Extreme Condition in 2006, became the default engine across Capcom’s internal development divisions, and was superseded by RE Engine from 2017. Capcom has never offered it publicly, and the most recent commercial release identified on it is a compilation from May 2025.

Why Capcom Built Its Own Engine — and Turned Down Unreal

The origin story is more interesting than the usual “studio builds engine” account, because Capcom seriously considered not building one.

Before MT Framework, each of Capcom’s internal teams used its own engines and tools, which the company judged inefficient. The obvious fix was to license someone else’s technology, and Capcom evaluated Unreal Engine 3 for the role. It decided against it on two grounds: performance limitations, and the difficulty of getting technical support from Epic Games — an American company — in Japan.

So development continued in-house instead. By contemporary Japanese technical coverage, it started in September 2004 with a single programmer, building on the Onimusha 3 engine, and grew as more platforms were added. The engine was deliberately built around PC development tools and initially targeted the Xbox 360 because of its similarity to the PC, which meant games could be written on PC first and then adjusted for console hardware.

That decision — reject Unreal, build for multithreading, develop on PC — is the whole reason “MT” means Multi-Thread, Meta Tools and Multi-Target simultaneously.

The Versions, and What Each One Changed

MT Framework 1.x (2006–2009) shipped Dead Rising (1.0), Lost Planet (1.1 on Xbox 360, 1.2 on PC), Devil May Cry 4 (1.3) and Resident Evil 5 (1.4). Its notable features were a light “2.5D motion blur” to smooth 30 fps games, Light-Space Perspective Shadow Maps with percentage-closer filtering, HDR rendering, soft particles, variable MSAA, Havok for general physics and a custom physics engine for cloth and inverse kinematics. The PC release of Lost Planet was the second PC game ever to support DirectX 10, and Resident Evil 5 became the first game presented fully in stereoscopic 3D including cutscenes.

MT Framework 2.0 (2010) began development in January 2008 and debuted with Lost Planet 2. Capcom rewrote several parts from scratch, which improved PlayStation 3 performance — the original had been built Xbox 360-first. It also hid hardware and shader-model specifics from programmers, letting them write more platform-agnostic code. Capcom’s 2011 annual report put 80% of the development process as common across Xbox 360, PlayStation 3 and PC. This version was also the first that external contract studios could use, starting with Marvel vs. Capcom 3.

The Dragon’s Dogma update (2012) was the most structurally significant. Earlier MT Framework games were stage-based with loading screens between them; Dragon’s Dogma‘s open world was tens to hundreds of times larger, so the engine was adapted to page parts of the world in and out of memory. It also moved from a forward renderer to a hybrid using deferred lighting, which is what made a 24-hour cycle, weather variation and an effectively unlimited number of lights possible. Resident Evil 6 built on that with SSAO, improved hair rendering and facial animation.

MT Framework Lite targeted Wii and PlayStation 3, starting with Sengoku BASARA 3. MT Framework Mobile, based on 2.0, targeted the Nintendo 3DS, PlayStation Vita, Android and iOS — and was good enough that Resident Evil: Revelations on 3DS ran a rendering pipeline Capcom described as almost identical to Resident Evil 5‘s.

MT Framework 3.0 (2018) powered Monster Hunter: World, with HDR output. That game is the interesting outlier: RE Engine already existed, but Capcom chose MT Framework anyway, saying the custom Monster Hunter toolsets built into it over previous games would benefit the project more than the newer technology.

What Replaced It: RE Engine, and Then REX

RE Engine arrived with Resident Evil 7: Biohazard in 2017 and is documented as having been developed from MT Framework 2.9 — an evolutionary successor rather than a clean-sheet design. One correction worth making while we are here: “RE” does not stand for Resident Evil. It stands for “Reach for the Moon”, which is what the engine’s logo depicts.

Capcom’s own Integrated Report sets out why the change happened, and it is not that MT Framework failed. The company writes that MT Framework “made it possible to efficiently develop high-quality games,” but that the pace of change and the growing size and complexity of games meant a new foundation was needed — so during Resident Evil 7‘s development, the engine team worked alongside the game team to build RE Engine.

The decisive line for anyone wondering whether MT Framework is still in play, from Capcom’s 2025 report: “Today, we use this engine to create all of our titles.” Capcom notes that one engine now covers everything from the photorealism of Resident Evil Requiem to the stylised look of Monster Hunter Stories 3, and that RE Engine’s efficiency let it launch both Street Fighter 6 and Kunitsu-Gami on Nintendo Switch 2 at the console’s June 2025 debut.

And REX? In October 2023 Capcom announced a next-generation engine codenamed REX — “RE neXt Engine” — aimed at handling far larger asset volumes, better per-project customisation and easier collaboration with overseas developers. But it is not a clean break: rather than switching engines again, Capcom is incrementally folding REX technology into the existing RE Engine. There is no “RE Engine 2” moment to wait for.

Games Built With MT Framework

The engine’s reach was wide enough that a complete catalogue would run to dozens of titles. The table below is a selection of the most significant or best-documented, by version.

One caveat on the version column: Capcom has not published internal engine-version labels for every title. Some of these are documented on box art or in credits, others are reported or inferred, so treat the precise numbers as indicative rather than official.

Handheld and mobile titles ran on the Lite and Mobile branches: Monster Hunter 3 Ultimate, 4 and 4 Ultimate, Monster Hunter Generations, the Ace Attorney games including Dual Destinies and Spirit of Justice, Super Street Fighter IV: 3D Edition and Sengoku BASARA 3.

The long tail is the surprise. After Monster Hunter Stories 2 in 2021, every subsequent MT Framework release has been a compilation — the Capcom Fighting Collection series being the last holdout, with Capcom Fighting Collection 2 arriving in May 2025. Everything else, including Capcom’s other retro compilations, moved to RE Engine.

Can You Download MT Framework?

No. MT Framework is proprietary and was never sold, licensed publicly or released as an SDK. There is no download, no pricing page and no public documentation. The publicly documented outside users are external contract studios working on Capcom projects — a route that opened with MT Framework 2.0 and was governed by commercial agreements, not a public licence.

What does exist is a modding ecosystem. MT Framework games store their assets in Capcom’s own archive formats, and the community has built extraction and model-import tools for them over the years. Those let you open and modify the contents of a shipped game. They are not the engine, they will not let you build anything new, and they are unsupported by Capcom.

If you want a comparable in-house-engine experience you can actually use, the closest licensable equivalents are Unreal Engine, or Godot if you want no royalties.

Key Takeaways

• MT Framework is Capcom’s proprietary C++ engine, in development since September 2004 and first shipped in 2006 with Dead Rising and Lost Planet.
• “MT” is documented as meaning three things at once — Multi-Thread, Meta Tools and Multi-Target.
• Capcom evaluated Unreal Engine 3 and rejected it, citing performance limits and the difficulty of getting support from Epic in Japan.
• RE Engine replaced it from 2017 — and was built on MT Framework 2.9. Capcom now states it builds all of its titles on RE Engine.
• “RE” stands for “Reach for the Moon”, not Resident Evil.
• REX, announced in 2023, is being folded into RE Engine incrementally rather than replacing it.
• The last non-compilation title was Monster Hunter Stories 2 (2021); the most recent release identified on the engine is Capcom Fighting Collection 2, May 2025 — nineteen years after its debut.
• There is no public way to obtain it. The only documented outside users were external contract studios working on Capcom projects, under commercial agreement.

Frequently Asked Questions

Conclusion

MT Framework is the rare in-house engine whose retirement is documented by its owner rather than guessed at. Capcom built it to stop its teams duplicating work, turned down Unreal to do so, ran it for a decade and a half across consoles, handhelds and phones, and then built its replacement on top of version 2.9 rather than starting over.

What is easy to miss is how gracefully it was allowed to age. Capcom did not move every project at once: Monster Hunter: World still shipped on MT Framework in 2018, two years after RE Engine was unveiled, and the fighting-game compilations stayed on it until 2025. That is a more sensible way to retire technology than most studios manage. For engines you can actually license, our directory of 100+ C and C++ game engines sorts the field by licence and category.
