mortal shell 2 game engine

Mortal Shell II runs on Unreal Engine 5.6. That version matters most for technical mod work and does not by itself determine frame rate, visual settings, or hardware compatibility.

Overview

The presence of Unreal Engine 5.6 would not by itself confirm ray tracing, upscaling, shader behavior, or a frame-rate target.

The character shell is essentially one mesh and notes that the original character has no facial bones or facial animation. These are modding observations, not a full asset-pipeline document.

Practical details

A short answer, Unreal Engine 5.6 is the technical claim preserved by the modding item. Modders should confirm the current executable, tools, and build before creating files.
