So for most of my time in GTA V I'm senselessly killing people, but about two weeks back I decided to try for 100% completion. I completed that task yesterday (by finishing golf below par lol) and I was expecting that to be the platinum trophy. I was incorrect and now know that it is "The Los Santos Legend". On PS4 it divides each section of trophies down, like GTA V, GTA ONLINE, etc. I only need five more offline achievements but I am worried that I will also have to complete the GTA Online section.
What do I have to do, achievement wise, to get the trophy?
