How to unlock the Aggravated Assault achievement in Batman Arkham City - Definitive Guide
After visiting all the locations, if some assaults did not appear (All will not appear in one fly though the city) then enter then exit a building to refresh the map.
It is also suggested that when you are looking for assault to fly around in detective mode. In my experience it seemed to make the assaults more likely to appear.
Thanks Kirblinx. Great solution.
These are very easy because you only have to fight one guy and he's never armed nor does he have any armor. In fact, you can pretty much always do a silent takedown if you sneak up from behind, but you really don't have to since the guy is so easy to beat.
You'll find these assaults in areas with lots of alleyways like the Industrial District, Park Row, and the Bowery. They will pop up randomly so there's not much sense in actively seeking them out. Just do them while you're completing the millions of other things there are to do.
If you happen to pass by an assault without realizing it, an objective marker will usually show up on your map for a certain amount of time if you happen to fly right over it. The objective marker is blank.
You can keep track of your progress by going to the map and hitting X for Side Missions. It'll be under "Arkham Assault" and will show you what percentage of them you have completed. The achievement will pop immediately after you get the last one.
FYI - You don't really get anything for these missions except XP and a grateful civilian.
I got this achievement after finishing the main game and nearly every other side mission while i was rounding up the last 20 or so Riddler Trophies.
When I was doing this again in New Game Plus, I had already finished the trophies so I had less reason to run around. That being said, A couple of the assaults wouldn't pop until after I had re-explored certain areas and beaten up leftover henchmen. The best example would be the museum. There are a couple of baddies left in there (make sure you check the War Room). Once I did that and left the museum, the last assault came up right around the corner to my right.
If you have any info or suggestions that may improve this solution, please comment below. Thanks!
Edit: I only had to use this during New Game +, they showed up just fine when I played through the first game.
One of the side missions involves beating up thugs who are bullying political prisoners in Arkham City. These are unmarked on the map and only appear when you get close in proximity to them. Once they are triggered, you will see and hear a “Local Surveillance” notification on-screen, with an audio clip of the thug and the prisoner. That side mission will then appear on the map as a pulsing white hexagon.
There are sixteen of these total. Most are in The Bowery and Park Row, with some being in Industrial District. None are in Amusement Mile. One of these is Jack Ryder, who is being beaten up before the Courthouse sequence. If you do not rescue him, a generic political prisoner will replace him in a different location.
The easiest way to find them is to use Detective Mode (, on PS3) to clearly see them through walls. Refer to the map below for their locations, marked in Yellow. Jack Ryder is marked with “JR”, while his replacement is marked with “Rp.”
Ever vigilant, stop all 16 random crimes in Arkham City (Arkham Assault). A crime is taking place when you are picking up hostile chatter in the Local Surveillance feed. Use detective mode to track who is talking, then knock out the henchman to free the Political Prisoner. The map will sometimes display a pulsing hexagon in the location of a crime even when you're not close enough to hear the chatter, so check your map often.
