WWE 12 (PS3): Can You Unlock The Rock with a Cheat Code? No

There are no cheat codes to unlock The Rock in WWE 12.

Why?

• Licensing: WWE controls likeness rights; developers can't add unlockables freely.
• Balance: Instant access to top stars ruins progression.
• DLC Model: Legends often sold as paid downloadable content.

Workaround

Use Create-A-Superstar to recreate The Rock's appearance, moveset, and entrance. It's the intended way to "play as him" if not on the base roster.
