While playing Resonance: A Plague Tale Legacy unlocks most of its achievements naturally, the Sea You Later! trophy is much easier to miss. Its description vaguely hints that you need to say hello to a turtle, which becomes nearly impossible to find on your own if you are already far along in the campaign. If you want to clean up your trophy list without running a full chapter replay, here is the exact location and requirement to unlock it.
To say hello to a turtle and unlock the Sea You Later! trophy in Resonance: A Plague Tale Legacy, players will need to revisit Chapter Three's subchapter "Paradise." This is the point in the story when Sophia arrives at Minotaur Island with Leni.
Right after the cutscene ends and you gain control of Sophia, you'll need to head left/west along the beach. Keep heading in that direction until you see some seagulls flying over something.
Once players approach the scene, the seagulls will fly away, and the creature will be revealed to be a sea turtle. This will trigger a small exchange between Sophia and Leni, as the turtle slowly crawls back into the water. Once the turtle is submerged in water, this will unlock the Sea You Later! trophy in Resonance: A Plague Tale Legacy.
