This also means that certain new features such as freelook are not planned, and that certain limitations of the original engine, such as the issues when attempting to load sprites, flats, and textures from different archives, are left in place. Static limits are raised and engine bugs are fixed on a case-by-case basis, as required to support the additional features introduced in the port without breaking demo compatibility. The actual Doom game code is contained in a DLL which is loaded by the Unity framework to run the game this allows simplified portability. Unity is merely used as a shell-more formally referred to as an abstraction layer-for handling input and output, while rendering is still performed by the original Doom engine. Although utilizing the Unity engine, this is a true Doom engine port, not a Unity recreation.
