Reach for the Moon: How Capcom's RE Engine Powers Almost Everything It Makes
From Resident Evil 7 in 2017 to Requiem, Pragmata and an Okami sequel, one in-house engine sits behind Capcom's remarkable run. Here is where it came from and what replaces it next.
Every great game studio has a secret weapon. For Capcom, it is a piece of software whose full name sounds like a poem: the Reach for the Moon Engine, better known as RE Engine. In less than ten years it has gone from one horror game to the backbone of almost everything the company makes, and 2026 has shown just how far it can stretch.
This year alone, Capcom has shipped Resident Evil Requiem (February, 89 on OpenCritic), Pragmata (April, 86), Monster Hunter Stories 3: Twisted Reflection and Onimusha: Way of the Sword (September, 85), all on RE Engine. A Resident Evil Code: Veronica remake and Mega Man: Dual Override are next in 2027.
Born from a failed engine
RE Engine was created in 2014, early in the development of Resident Evil 7: Biohazard. Capcom's previous engine, MT Framework, had powered the company's games through the PS3 era. Its planned successor, Panta Rhei, began development in 2011, but it was abandoned amid the troubled production of the online action game Deep Down, which never came out.
Capcom's explanation for building yet another in-house engine was blunt: a generic engine made by another company, it said, would not be appropriate for a game like Resident Evil 7. The studio wanted photorealistic horror, and it wanted full control over how to get there.
From one game to everything
Resident Evil 7 launched in 2017, and the engine spread quickly:
- 2019: Resident Evil 2 remake and Devil May Cry 5.
- 2021: Monster Hunter Rise and Resident Evil Village.
- 2023: Resident Evil 4 remake, Street Fighter 6 and Exoprimal.
- 2024: Dragon's Dogma 2 and Kunitsu-Gami: Path of the Goddess.
- 2025: Monster Hunter Wilds, which sold over 8 million copies in three days.
- 2026: Resident Evil Requiem, Pragmata, Onimusha: Way of the Sword and more.
That list covers survival horror, character action, fighting games, open-world role-playing and hunting games. Few in-house engines anywhere handle that much variety.
The engine's growing pains
Stretching one engine across so many genres has not always been smooth. Open-world games like Dragon's Dogma 2 and Monster Hunter Wilds drew criticism for demanding PC performance at launch, a reminder that an engine designed for tight corridors in Resident Evil 7 had to learn to draw huge, busy landscapes.
Bringing the engine to Nintendo hardware took work as well. Monster Hunter Rise director Yasunori Ichinose said a lot of background technical engineering was needed to run it well on Switch. Today, many RE Engine games are on Switch 2, including Resident Evil Requiem, which is one of the best-reviewed games on the console.
What comes next: REX
In October 2023, Capcom unveiled its next step in a 22-minute developer presentation: Codename REX, short for RE neXt ENGINE. Rather than starting over, as it did after Panta Rhei, Capcom plans to fold REX into RE Engine gradually, upgrading parts of the existing technology over time.
That approach makes sense for a company that is releasing several major games a year. Throwing away a working engine would risk exactly the kind of disruption that killed Deep Down. Upgrading it piece by piece keeps the release schedule intact.
Why it matters, and what's next
Capcom's run since 2017 is one of the best in the industry: hit remakes, a revived Monster Hunter, a fighting-game comeback and, this year, a horror launch that sold faster than any Resident Evil before it. Good games come from good teams, but a shared engine lets those teams share tools, staff and lessons. RE Engine is the quiet reason Capcom can do so much, so well, so often.
The next RE Engine releases on the calendar are the Resident Evil Code: Veronica remake and Mega Man: Dual Override, both in 2027, with the Okami sequel further out. In the meantime, Resident Evil Requiem is the engine at its best.
