It's a zipped (compressed) file.
File extension is .zip
File name is:
MaxPayne2_Theme.zip

If you can search for filename, look for it.
And when you find it, unzip the file (also known as decompress or extract.)
I'm not sure what Macs do when downloading files, but it's a 3.3 Mb file.
(roughly)

Found it on my desktop. Don't think I have anything to unzipper the thing!!
