How to unlock the Dial Z For Murder achievement in Batman Arkham City - Definitive Guide
When you get to the 2nd, you must trace the call to zzazz. You do this by following the marker around with the left thumb stick and keep it over the marker. You won't finish this on the first try. It will take about 4-6 times before you trace the call.
Once you trace him, go to his hideout, open the vent inside with your batclaw, go into the lair, circle around it and take zzazz down.
I do reccommend waiting till you get the batline before finishing this side quest, it was the only was I got through the last section of his small lair. You get the item after beating penguin and chasing down a ninja.
Thanks!
I'm sure there is another method, but I have not found it yet.
But if you were like me and decided to finish this as your last side mission, your probably thinking that you would end up waiting endlessly looking everywhere for a phone call to ring up. Well thankfully there's a helpful way to keep track on which phone might ring next.
Just click over to your map and go to your side missions menu, to click on Zzasz's mission. Once clicked, it should filter your map to have all the phone locations. How is this helpful? Well take note that each phone icon that you answered successfully is marked off. So basically just search for the phone icons that are left in the city for a possible ring, instead of checking randomly for one. Hope this helps!
You don't need the batline to get across to ZZasz, I managed to circle round to him by jumping and using the freeze blast.
This video by ShockblastMedia shows how it can be done, without the batline.
While you are running around the city, Z will call a phone booth nearby. Use detective vision to locate the phone, then answer it. Z will give you a another phone booth to reach in a time limit. I recommend using the map to find the goal, then run to it. It'll be another phone booth, so it will on the ground.
I had plenty of time on many of these, and got all of them on my first time. It's not hard. After each time you do this, there's a minigame. After 5 or 6 times, you'll find his lair. In his lair, there's a lot of jumps that aren't too hard. For the final jump, you need to use the line launcher, then drop and quickly grapple away. The timing is tight on this.
Side Mission – Cold Call Killer.
Before you can even attempt this trophy, you will need to pick up the first phone that you hear ringing. This will introduce you to Victor Zsasz. Once picked up you will gain Ring Ring . Now that this side mission is activated, you will be free to pick up any other phones, these phones are random and ring at any given time. There will be a HUD in the game directing you to where a phone will be ringing.
There are two parts to this side mission. Once you hang up the first call, you will be given an allotted time to get to the next phone that's ringing. Once picked up, you will be attempting to trace the call do this until the bar in the top left reaches 100%.
Once at 100%, the hideout will be pinned on your map.
Once at Zsasz hideout. Follow the route round to the middle, then use a takedown on him ().
For a visual map of the locations of the phones, refer to the following picture:
