This "mod" is my save file from the game. Not really willing to replay that part just for one achievement? Nevermind!

Where should I put the save?

YOUR INSTALLATION FOLDER\Half-Life Alyx\game\hlvr\SAVE\s1

Okay, save is placed. How do I get the achievement?

You can find gnome under your right foot. Just grab him and walk towards the beam. Achievement should unlock after that.

Why are you just giving away your save file?

Look at my Nexus profile, this isn't first game I have put save files on nexus.

*Don't forget my comment section isn't democracy. In the past few people expressed themselves in negative way about my save files - If you don't like this save file because "others should work for it" - your comment will be deleted.
