While our tools and engine APIs are mainly focused towards making great 2D games the engine itself is fully 3D and we do have a Model component for loading 3D models and animations. The model component paired with a perspective projection camera and you have the basic building blocks for creating 3D games.
We have in our roadmap to improve 3D support in the engine and editor to make it easier to create full 3D games. But we will likely never really compete with Unreal and other more 3D centric game engines.
