Notes and Comments
- File format is used by Slayer Engine developed by The Collective (now Double Helix Games) company.
- It seems that format has evolved over the years and there are some differences in specification for games using Slayer Engine.
- Files inside PAK files may be compressed with LZO compression (Silent Hill: Homecoming).
