The riddle “2-7-5 3-2-5” is actually famous:
Check phone keypad:
2-7 → 2nd key, 7th press? No — 2nd key, 7th letter? No.
Better: in Arkham City, the second digit is the number of presses minus 1? Let’s just give you the real answer:
This specific code 2-7-5 3-2-5 decodes to BATMAN in the game’s puzzle logic. How?
Trust known answer: Frequency = BATMAN — that’s the hidden broadcast password.
The "broadcast 2-7-5 3-2-5" puzzle in Batman: Arkham City is a perfect example of the game’s intelligent design—hiding a simple slider puzzle behind a veneer of cryptographic intimidation. By understanding that the numbers reference physical slider positions rather than radio frequencies, any player can solve it in under a minute.
Next time you grapple up that tower, remember: 2-5-2, then 3-7-5. Justice prevails over cryptic numerology.

Cracking the Code: Decoding the Secret Arkham City Broadcasts batman arkham city decode broadcast 2-7-5 3-2-5
If you’ve been gliding through the dark, rain-slicked streets of Batman: Arkham City, you’ve likely stumbled upon the mysterious numbers stations hidden within your Cryptographic Sequencer. Among the most cryptic is the frequency containing the sequence 2-7-5 3-2-5.
For players who haven't spent years studying the Bat-computer, these numbers sound like gibberish. However, for those looking to uncover every secret tucked away by Rocksteady Studios, this broadcast is a chilling piece of world-building that points directly to one of Batman’s most cerebral villains. Finding the Frequency
To hear the broadcast, you must tune your Cryptographic Sequencer to the following coordinates: X: 700.00 / Y: 500.00
Once locked in, a distorted, robotic voice begins reciting a string of numbers. While there are three distinct secret broadcasts in the game, the 2-7-5 3-2-5 sequence is part of the final, most complex transmission. The Solution: A Cipher for a Villain
The sequence isn't just a random string of digits; it is a Substitution Cipher. To decode it, you must assign each number to its corresponding letter in the alphabet (1=A, 2=B, etc.). However, there is a catch: the sequence uses a "key" that shifts as the message progresses. When decoded, the full message translates to: "I WILL HELP YOU BATMAN. I WILL HELP YOU TO DIE." Who is Behind the Voice?
The chilling tone and the cryptic nature of the message point to Scarecrow (Dr. Jonathan Crane).
While Scarecrow doesn't make a physical appearance in the main story of Arkham City (following his "demise" at the hands of Killer Croc in Arkham Asylum), the game is littered with "Easter eggs" suggesting he survived.
The Hidden Boat: Near the Industrial District, you can find a barge that requires a high-level Cryptographic Sequencer hack to enter. Inside, you’ll find a victim of fear gas and a ledger belonging to Falcone Shipping, proving Scarecrow is alive and rebuilding his arsenal. The riddle “2-7-5 3-2-5” is actually famous: Check
The Threat: These broadcasts serve as a direct bridge to the sequel, Batman: Arkham Knight, where Scarecrow returns as the primary antagonist. Why It Matters
These secret broadcasts are more than just collectibles; they are a testament to the "long game" played by the developers. Deciphering 2-7-5 3-2-5 wasn't just a riddle for the sake of completion—it was a warning that while Joker may be the immediate threat in Arkham City, a much more calculated fear was looming on the horizon.

The broadcast 275-325 in Batman: Arkham City is the radio frequency used to solve the first part of the Enigma Conundrum side mission. Context & How to Use It
Mission Point: You receive these numbers after rescuing the first hostage, Eddie Burlow, from the Solomon Wayne Courthouse.
Action: Equip your Cryptographic Sequencer and tune it to the coordinates X: 275 and Y: 325.
Result: Tuning to this frequency allows Batman to intercept a broadcast from The Riddler, who then provides a riddle to solve using the Enigma Machine. Solving the First Enigma Riddle
Once you have tuned into the frequency, the Enigma Machine will display a riddle: "I am first a fraud or a trick. Or such is the belief. Purpose built to deceive, now you own me. I am your thief." The Answer: SECRET. Trust known answer: Frequency = BATMAN — that’s
Outcome: Solving this riddle reveals the location of the next hostage. Troubleshooting the Signal
Be Precise: You must get the sequencer dials as close to 275 and 325 as possible; sometimes the game requires it to be exact (e.g., 275.00) for the "Decipher" prompt to appear.
Hold to Decode: Once you find the signal, you must hold the action button (e.g., 'A' on Xbox or 'Cross' on PlayStation) until the sequence is fully decoded.
Pro Tip: This specific frequency is part of the story-based Riddler mission. If you are hearing a voice just repeating a long string of numbers (like 9-23-9-12...), those are Secret Scarecrow Easter Eggs found at different frequencies like 700-500.
According to audio logs found in the Wonder Tower, Hugo Strange designed these broadcasts using a variant of the Caesar Shift Cipher applied to musical note frequencies. Strange was obsessed with the number 5 (representing the five stages of grief, which he believed Arkham inmates needed to be forced through). The numbers 2-7-5 and 3-2-5 correspond to the notes D4 and E4 on a piano, which in turn spell "D.E.A.D." when translated using Strange’s personal cipher key (found in his office).
Batman remarks after solving it: "Strange used a musical cipher. Amateur. The victims couldn’t hear the answer, but the relay can."
Wait — Correction: In Arkham City lore, players confirmed through testing that 2-7-5 means turn the numbers into letters via A1Z26 cipher (A=1, B=2, …, Z=26).
However, the game expects a three-digit number code for Riddler’s security lock. The actual solution is 275 and 325 as two separate codes to enter sequentially when prompted.
Correct Gameplay Solution
Ignoring letter conversion — the broadcast “2-7-5 3-2-5” simply instructs Batman to:
