See, I never used gameshark after it screwed up my PS2. Kept reading the disks incorrectly and after that I wouldn't dare use it on my PS3. It sounds interesting for zombie mode but don't feel like worrying about my system all over again.
aww, but wouldn't it be fun to beat up on the AI as a zombie? *evil grin*
