The Vanishing of Ethan Carter Redux is an Unreal Engine 4 remaster of the original PC game. It is a free game for the current and future owners of the original.

You should already have the game in your Library. It's a separate game from the original (i.e. not a patch) because this way you can choose which one takes your HDD space. You can hide the other one by right click, then Set Categories, then Hide This Game From Library.

Details here in this blog post.
