It's another person's attempt at remodeling a level from a Nintendo game in Unreal Engine 4
Although it looks almost breathtaking and similar to the Kakariko Village, the game when finished will probably be treated just like the Super mario 64 remake was, it'll be taken down and built for nothing. So why do people keep making things like this with no reward?? I believe they may just desire the challenge. Perhaps if they actually took their plans to Nintendo somehow they might be able to work out a deal, but sadly a copyright is a copyright and Nintendo are the copyright holders...
Game on and Keep it Rehl!
