When I try to open the zip, I get an error
"Unable to expand "Luna_Interficere_MacOS.zip" into "Downloads". (Error 2 - No such file or directory.)"
This might just be client side, thanks for trying though!
Go to your terminal then type Unzip then drag the zipped file into the terminal. It should unzip it and leave the file in your users folder. I had this problem on my macbook with other zipped files before.
