Batman: Return to Arkham - Arkham City

The Campaign Challenges function the same way as Batman's and you do have to complete all of them again as Nightwing, plus the extra challenge with Nightwing's maps. They are the same challenges that you've done before, so they shouldn't give you too much trouble. These are the modifiers that I used. You can make your own combinations if these aren't working for you, but they worked well for me. Remember, you only get three retries total, but you get unlimited retries on the first challenge room.

You can also use KingBroly's guide for the modifiers since they will work too.

Note: The challenges that you have to do for the trophy are the same ones that you had to do as Batman, plus the Nightwing campaign. The following challenges DO NOT count for the trophy. Any medals that you get in them will not matter.

Special Notes:

• For Lost City with Robin, you cannot use One Hand Tied since you need to do a silent takedown. Use One Hand Tied on Top of the World instead.

Special Notes:

• For Police Brutality (Extreme) with Robin, don't use Danger Zones. Two for Two will be much easier without Danger Zones active. Swap Scattered Weapons and Danger Zones for Robin.
• The set up to use with Nightwing is the following: Police Brutality (Extreme): Time Limit, Increased Aggression, Scattered Weapons. Natural Selection (Extreme): Protective Aura. End of the Line (Extreme): Danger Zones, Free Medal.
