The MT Framework engine was widely used by CAPCOM all the way from 2006’s Dead Rising to 2015’s Dragon’s Dogma Online. After that, it was mostly remasters like Resident Evil Zero HD Remaster and Ultra Street Fighter II: The Final Challengers.

With Resident Evil VII: Biohazard launching in early 2017 powered by the brand new RE Engine, MT Framework was thought to be on the way out for future games. However, CAPCOM surprisingly announced that Monster Hunter: World, the highly anticipated action RPG co-op hunting game coming to PlayStation 4, Xbox One and PC, would still run on that engine.
