Here's the breakdown:
Cold Transferring a Call (Customer Service Practice):
In the real world, a cold transfer is when a customer service representative connects you directly to another department or person without speaking to them first. This can be frustrating as the transferred person wouldn't know why you're calling or what you need.
Victor Zsasz ("Cold Call Killer" in Batman: Arkham City):
Zsasz is a Afghanistan Phone Number List serial killer in the game who targets random people and uses a payphone to call Batman before each murder. These calls are often taunting and filled with philosophical musings about life and death. However, Zsasz doesn't actually "cold transfer" anyone.
The Connection:
The name "Cold Call Killer" might be a playful reference to the concept of cold transferring. Zsasz's random, unexpected calls could be seen as a twisted version of a cold call, where the "recipient" (Batman) has no idea who's calling or why.
Additional Notes:
Completing Zsasz's side mission in the game involves tracking down these payphones and answering his calls.
The game doesn't explicitly mention cold transferring, but the name "Cold Call Killer" suggests a connection to the real-world practice.
