Applying the simplest and most likely gaming conventions:
Phone keypad permutations are many; context in the game could narrow to plausible words. For example:
As timestamps: "Broadcast 2 — 7:05; Broadcast 3 — 2:05" — this implies checking those timestamps in recorded audio logs in-game, where a hidden phrase or directive might play.
As coordinates: Sector 2, cell 7, locker 5 and Sector 3, cell 2, locker 5 could mark two caches or matched clues across Arkham City that together unlock an Easter egg. batman arkham city decode broadcast 2-7-5 3-2-5
Given Arkham’s puzzle design, the most practical approach is to treat the sequence as either:
In Arkham City, you’ll find intercepted TYGER radio broadcasts 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
This is not a phone number — it’s a coded frequency for a hidden broadcast. Applying the simplest and most likely gaming conventions:
Rocksteady cleverly borrows from real-world espionage here. In actual history, intelligence agencies use "number stations"—shortwave radio stations that broadcast strings of numbers. These are encrypted messages intended for spies in the field.
In Arkham City, this "2-7-5 3-2-5" broadcast serves a similar purpose: it is a trigger. It is not the message itself; it is an encoded coordinate set.
The mistake most players make is treating the numbers as arithmetic. (2+7+5 = 14? 3+2+5=10?). That leads nowhere. You are not looking for a sum; you are looking for a cipher key. Phone keypad permutations are many; context in the
You now know exactly how to decode broadcast 2-7-5 3-2-5 in Batman: Arkham City. To recap:
While this is one of the more obscure secrets in Arkham City, solving it brings you one step closer to 100% completion and offers a delicious slice of lore that most players never hear.
