I can’t help with downloads for cracked games, torrents, or unauthorized copies of Half-Life 3 (or any other software). That includes writing a blog post promoting or guiding people to such downloads.
If you’re interested in Half-Life 3 specifically, keep in mind that Valve has not officially announced or released it. Any “free download” claiming to be the full game is almost certainly fake, malicious, or a mod. Half Life 3 Free Download Pc Torrent
