Where can I find the intro sky from the original Showdown release?

The original release of showdown had a brief environment with the UE4 logo and a sky full of lightning. When I download it now, the logo is just shown against a black background, on botht the 4.9 version and the 4.10 version. Is there anywhere I can download the original release? I had planned to use the sky in an environment, and already exported it to one temporary project, which I’ve since deleted and lost the files for.

You can still see the old intro environment in the thumbnail of the project, but I don’t see it in the project itself anywhere anymore :

I actually have the same issue here. Before when I’ve demo’d this project to people it had that nice intro, and now it’s just black and the character starts with a base height of 0 AND it doesn’t run smoothly anymore.
