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

Where should I put the save?

C:\Users\YOURUSERNAME\Documents\Horizon Forbidden West Complete Edition\YOURSTEAMNUMBERS

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

Depends. For this achievement, you have 3 options.
First is to get whatever gear you wanna and go full last mission.
Second is after killing Erik, so only final boss.
Third is after final boss, just walk forward and enjoy. Achievement should pop after cutscenes and credits.
Since I played on hardest difficulty, you will also get achievement for ultra hard difficulty.

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.
