These are the Secrets and Unlockables in Silent Hill: Homecoming.
Secrets
Alex makes a keen observation.
- Examining a missing photo will result in a reference to a famous message in Neely's Bar.
- Some of the books in the Shepherd House seem to have odd titles, although they are extremely blurry and difficult to read. They appear to include "A Book Title", "An Interesting Book Title", "The Collective", "Harry Got His Gun", "Life is a Bore", "Rocket Science for Dummies" and "Anal Sex for Dummies".
Achievement references
Several of the Achievements unlocked through the course of play reference previous Silent Hill games.
- Eddie's Legacy: This achievement is obtained upon killing a Feral for the first time This is a reference to Eddie Dombrowski's murder of a dog while angry.
