This video shows and explain all the cheat codes for Batman: Arkham City known to date:
0:00 - BIG HEAD MODE With the "Big Head Mode" cheat every character in the game (Batman, Catwoman, Robin and Nightwing included) will have big head, big hands and big feet.
The cheat only works when you complete all the story missions in Normal or Hard difficulty. It can be enabled also in New Game Plus mode and during Riddler's Revenge challenge maps.
There are two methods to activate this cheat.
The first method works on both PC and console versions of the game:
PC: Up, Up, Up, Down, Down, Down, Left, Left, Right, Left, Left, Up, Up, Down (or W, W, W, S, S, S, A, A, D, A, A, W, W, S)
Console (Xbox 360 and PlayStation 3) - using the D-pad: Up, Up, Up, Down, Down, Down, Left, Left, Right, Left, Left, Up, Up, Down
The second method works on console and PC, but only if you're using a gamepad: Hold down LT and RT on Xbox 360 or L2 and R2 (or L1 and R1) on PlayStation 3, then move the right analog stick clockwise and the left analog stick counterclockwise at the same time, until you see the Big Head Mode activated.
With this method the Big Head Mode can be applied to the characters shown in the main menu.
To remove the Big Head Mode just repeat the cheat or restart the game.
3:41 - TAUNT / ACTION CAMERA CHEAT With this cheat, Batman (or Catwoman, Robin and Nightwing) will do a "taunt" similar to what they do at the beginning of a challenge map or a round.
This cheat works on console and PC, but only if you're using a gamepad.
To activate the cheat you need to spin the right stick clockwise two or three times.
If you're using Batman or Robin, the Taunt cheat can also activate an action camera when you perform a glide kick from a vantage point. Do the Taunt movement then press the Glide Kick button to see the effect.
