4 5 3Actions Report Solution Just upgrade one of your weapons fully. It may take some time as some of the weapon's upgrades don't unlock until late in the games story progression.Showing all 3 comments. Leave a comment. 1st playthrough I had fully upgraded 1 weapon with all mods and achievement did not pop. I only got the achievement for doing it for all of them but not this one. On 2nd playthrough, I did not upgrade anything on my bow until I got all the automatic upgrades/mods you get from the story and still did not get no achievement.Posted by Mr PullOut711 on 25 Mar 23 at 22:02 I also have the same problem every weapon is 100% done and I didn’t get it.Posted by KaylaJay89 on 07 Jul 23 at 17:28 Not unlocking.
