Hidden In Plain Sight is the trophy for Far Cry 6's secret ending, where you find your way to Miami early in the story. It is missable and needs one choice at the right moment.
Libertad RisesLibertad Rises is the last Isla Santuario operation, where you clear the Quito Bay blockade so Clara's boat can reach the mainland. Finishing it gets you off the starting island and opens the rest of Yara.
The GuerrillaThe Guerrilla is the first stop on the main island, where you reach Libertad's base in the Zamok Archipiélago and see Juan's workshop. It opens the three regional storylines.Early on, the game gives you one chance to leave Yara for Miami instead of going on with Libertad. Take it and the secret ending plays, then the trophy pops. Reload afterwards and carry on as normal.
Once Libertad Rises is done, do not start the next operation, The Guerrilla. Board the boat instead, and the secret ending starts.
Keep a save near this point. If you have already played past it, you need a new game to get the trophy.
