Batman: Arkham City PlayStation 3 Cheats and Tips

To find a secret hideout, climb to the top of the boat in the industrial district, by two cranes.

Once there, use the Cryptographic Sequencer and manipulate the letters until the message "City Of Terror" is displayed.

A secret path will appear on the boat, allowing you to climb down into a infested hull. You can pick up a medical form for Jonathan Crane and see a scarecrow that reacts when you zoom in on him.

To get a second hidden message, use the Cryptographic Sequencer and get coordinates 500,900.

This will return the following numbers:

5-15-9-7-21-18-18-14-3-5-24-15-12-7-22-3-10-5-15-9-22-3-8-25-26-15-16-25-10-15-17-25

To decode it, use the following number pattern, where 1 = C, 2 = B, 3 = A, 4 = Z, etc.

Once you have worked out the code, it will read: "YOU WILL PAY FOR WHAT YOU HAVE DONE TO ME".

Search the coordinates X: 200.00, Y: 500.00 on the Cryptographic Sequencer to unearth a hidden message to decode.

Message: 3-20-26-18-26-16-24-1-11-4-24-9-3-8-5-2-12-18-6-16-7-11-3-10-17-5-13-4-21-8

Decoded message: 'FEAR WILL TEAR GOTHAM CITY TO SHREDS'

Search for the coordinates X700, Y490 on the Cryptographic Sequencer to intercept a radio frequency that contains the following repeating numbers: 9, 23, 9, 12, 12, 18, 5, 20, 21, 18, 14, 2, 1, 20, 13, 1, 14. The message is decoded as 'I WILL RETURN BATMAN'.

To unlock the alternative ending for Arkham City, you need to have access to the Catwoman DLC. With this done, on Catwoman's third mission, head right when you are given the choice of right or left.

This will set up the alternate ending - remember that you can revert following this so it doesn't change the rest of the main game.

You can make Batman's (and everyone else's) heads ginormous by using the cryptographic sequencer and holding L1 and R1.

Rotate the left analog stick anti-clockwise, and the right clockwise.Soon, you will see Batman's head become much larger - as will all your enemies'!

When the game has been completed under the Normal or Hard difficulty setting you will be able to retain any previously earned Experience points and gadgets. In New Game Plus mode there will not be any counter icons on thugs and they will have different configurations and be tough to defeat from the start of the game. The Bosses will also be tougher.
