Continue the game and go to Chinatown 2 and collect the last unlock for Completionist. Here is the location.
Go to "Alleys 1" and collect the first and last hidden tag for the Tag Collector trophy.
You can also unlock the rest of the trophies with this save. The only ones you have to do work on are Pacifist, Unkillable, and Graffiitti Partner. Beat the boss levels to unlock their respective trophies. Credits to me for the save.
