Lord of the Rings fans are doing a remake of Battle for Middle Earth in Unreal Engine 4, which looks almost like a new game.
This project is The Battle for Middle-Earth: Reforged, and it has the same name as the original title, however, the remake means that they had to rewrite all the code in the game. This means that there may also be certain changes to gameplay compared to the original title.
The project team hope to add more to the remake such as terrain that can be destroyed, 4K support, and hope to release a playable version in the early months of 2019. Unfortunately, currently there is no single player option that will be available, as the game will only support multiplayer.
