Hi there! Unfortunately, there is only a project file for Unreal as stated on the page. I would love to make a Unity scene as well, but it's pretty complex, and I'm primarily an Unreal user, so I would have to figure out how to replicate everything for a different engine. At half price, you get all the assets, including the Blender file, so you could contact support for a partial refund. I will try and update the page to be more clear about what you get so there's no confusion.
