As the easy download extract and run link from the OP is dead, I have decided to upload WA.ZIP as a torrent file to keep it from dying.
You can download it on
The Pirate Bay or directly, using the magnet link magnet:?xt=urn:btih:6ebbf87f2cb20d0c685827e916d058561221236c&dn=Worms+Armageddon+Project+X+Extract+and+Run&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Fzer0day.ch%3A1337&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Fexodus.desync.com%3A6969 - just copy and paste into a browser or a torrent downloader.
I will try and seed the file constantly, but if you find that there's no active seeders you can expect me to continue seeding it shortly.
