Press Start on controller one to pause game play in story mode, then press L1, R3, R1, L3, Right, Square, Up, Square, L2, Left, Square, Down, R2 on controller two. The game will automatically resume to confirm correct code entry. Have player one walk towards an enemy or innocent. When close enough, player two should be able to control him/her. Note: Enabling this code may glitch the game. This code gives player two complete access to every enemy at once. When the code is enabled when near an enemy with the "?" on radar (meaning they do not know you are there), you will be able to use simple basic controls with controller two, using the D-pad. Press Left or Right to rotate all enemies on the map. They rotate similar to a character in a Resident Evil game. Press R1 to make all enemies duck. Press X to make them all jump. All enemies can also double jump. Press Forward to will make all enemies on the level move forward. They cannot attack if the code is enabled in the "?" state. Doing the code when an enemy is in the "!" state will allow player two to access all enemies in attack state. All enemies on the level will be able to do the same thing as "?" state enemies, but will be able to attack with Square, and will be be able to move backwards with the D-pad. Enemies do not hurt other enemies; only you. You can now also block attacks with all enemies. Repeat the code to disable its effect. The best use of this code is for stealth killing everybody, as when the code is enabled, enemies do not have an active AI and will no longer react to you on sight, even if you hit them. You can also force enemies off ledges and cliff sides.

You can toggle enemy's attack mode by pressing L3 on controller two.

Note: This will also cause enemies to not attack you if you approach them.
