Multiple Endings
Hollow Cocoon features four distinct endings that result from player choices throughout the story. Decisions made during key moments branch the narrative, leading to different conclusions and revealing varied aspects of the underlying mystery.
Because the endings are tied to narrative branches, replaying the game with alternative choices can expose new story details and outcomes.
- Consider saving before major decision points to compare outcomes.
- Take note of which evidence you collect; it can influence ending paths.
