Found something cool

I found this and I want to see it but the compression is unknown and the file will not extract.
anyone else able to extract it?

Get WinRAR:

That’s an impressive ship, but wouldn’t this be better suited for the Garrysmod.org section:

As for the unknown compression they’re zip files, could it have to do with your OS?

It extracts for me in WinRAR.
