Star Wars Outlaws

Story-related, cannot miss.

Once you've completed all the main quests on Toshara, Kijimi, Tatooine and Akiva, you'll be entering endgame territory. The next quest, “The Truth,” will form a temporary point of no return (until after you've completed the game's story) and will set you on the path to learning Sliro’s big secret. 

Complete that mission and this trophy is all yours.
