In Arkham City , you’ll find as part of the “Communication Breakdown” side mission (or similar Riddler‑related intercepts). The broadcast will be a series of number pairs like: 2-7-5 3-2-5
: Save Medical Protection Team (M.P.T.) officer Eddie Burlow.
Understanding how to intercept this transmission, decode the message, and track down the subsequent puzzle locations is essential for players aiming to rescue all of Edward Nigma’s hostages and achieve 100% completion. Intercepting the 2-7-5 3-2-5 Signal
However, the game expects a for Riddler’s security lock. The actual solution is 275 and 325 as two separate codes to enter sequentially when prompted.
Once you have successfully locked onto the frequency, the broadcast automatically feeds a riddle into Batman's Batcomputer interface. To advance the mission, you must use the cryptographic wheels to spell out the text answer to his query. The First Riddle
Think of the in-game map as a grid:
Batman cut the feed. He had the numbers. Now he just needed the truth.
In Arkham City , the Riddler frequently uses “ENIGMA” or “RIDDLER” as base keys. However, for this specific broadcast, the game’s internal guide points to the phrase: “THE PEN IS MIGHTIER THAN THE SWORD” (a clue found on a nearby riddle trophy).
| Key | Letters | Presses | |-----|---------|---------| | 2 | ABC | 1=A,2=B,3=C,4=A,… | | 3 | DEF | 1=D,2=E,3=F,4=D,… | | 4 | GHI | 1=G,2=H,3=I,4=G,… | | 5 | JKL | 1=J,2=K,3=L,4=J,… | | 6 | MNO | 1=M,2=N,3=O,4=M,… | | 7 | PQRS | 1=P,2=Q,3=R,4=S,5=P,… | | 8 | TUV | 1=T,2=U,3=V,4=T,… | | 9 | WXYZ | 1=W,2=X,3=Y,4=Z,5=W,… |
Because Batman: Arkham City heavily utilizes radio frequencies for hidden secrets, players looking up "decode broadcast" often mistake the Riddler's frequency for the hidden . If you are looking for the hyper-complex, creepy voice clips broadcasting raw numeric lists that require alphabetic shifts, you are dealing with a completely separate Easter egg.
: Once you enter the frequency into your Cryptographic Sequencer , it connects you to the Riddler's "Enigma" machine.
To rescue all the hostages and confront the Riddler face-to-face, you must scan and collect a minimum number of scattered across Arkham City. Each milestone forces Oracle to decipher the next radio frequency.
