Siren Codebreaker Codes (NTSC-U)
This page contains all of the CodeBreaker cheat codes I have for Siren (NTSC-U). If you're playing with the PCSX2 Emulator and you'd like to use the codes on this page I recommend heading over to my How To Use Cheat Codes on PCSX2 Guide. This will explain how to setup and use the codes on this page with that emulator.
Alternatively if you're playing on a physical console you'll need to own a CodeBreaker/GameShark disc in order to use these codes. If you don't see the code you want on this page I recommend you return to my Siren Guides Index and choose a different section.
