Batman Arkham City - All the secrets and easter eggs

Batman's secrets.

Here we are in the usual appointment with secrets, easter eggs and various curiosities more or less hidden by the developers in video games. This time it's the turn of the beautiful Batman Arkham City.

 

SPOILER! in the next lines you could read details of the game's plot. Avoid reading if you haven't finished the game yet and don't want to ruin the story.

 

1. The hidden sequence with Killer Croc
After you defeat Ra's al Ghul and are about to leave the subway tunnel, instead of going the right way, go back until you find a gate blocking the passage. You should see a button on the back wall and an empty space between the iron bars. Throw the Batarang through the crack to hit the button. There will be a Killer Croc cutscene. Here is a video that shows it all.
Please note: it will no longer be possible to reach this area after this point in the game.

2. Reference to the LOST TV series
During your second visit to the steel mill you will see Joker on a big screen and you will be able to hear one of his many delusions. If you pay attention you will see that in the speech there are precise references to the television series LOST such as: "How come it all ended up in a Church" or "I don't remember, but did they ever say what the island really was?"

3. Reference to Star Wars
There is a Lightsaber, the Star Wars lightsaber in the box with weapons that Batman finds in the Deadshot side mission.
Without doubt this is a tribute to Mark Hamill, who voices the Joker (English) in the game, in relation to his role as Luke Skywalker in the original Star Wars trilogy. Here is a video showing this Easter egg.

4. Secret messages
Use Batman's Cryptographic Sequencer to go to the following coordinates and intercept secret radio transmissions that spread numbers, emit a buzz, and then repeat the same numbers. By combining these numbers with the corresponding letter of the alphabet, the message is decrypted.
Please note: some of the secret broadcasts may not be available until after completing the main campaign. Here are the secret messages:
