Rule of the Internet do not trust anyone and it’s always wise to scan anything you download from Internet.

Dont be mad at me but I bought the game from GOG :)

Just in your torrent client add magnet like this (replace info hash with one from website) magnet:?xt=urn:btih:INFOHASH

For example, if your infohash is 1234567890abcdef1234567890abcdef12345678, the full magnet link would be magnet:?xt=urn:btih:1234567890abcdef1234567890abcdef12345678
