Batman: Arkham City Steel Mill Riddler Trophy Locations

Finding this trophies will take a lot of exploration time.

The Steel Mill found in the western ends of the map holds 24 of the Riddler Trophies for you to hunt in Batman: Arkham City. Although the Steel Mill may seem quite understanding but it holds many secret passages and puzzles where you could find these collectibles to complete the Riddler Challenges.

These Riddler trophies are quite similar to Catwoman’s trophies, however, Batman’s Riddler Trophies will be green compared to Catwoman’s pink color.


You can collect all of Batman’s trophies while playing as Catwoman but won’t be able to do it vice versa.

You can choose to find out all 24 locations of these trophies by interrogating one of Riddler’s goons but that can result in some precious hunting time being wasted. So, we went ahead and marked all of the locations on the map and even went a step ahead with explaining how to get each one of them.

Before we dive into these Riddler trophies, we recommend completing the main storyline of the Batman: Arkham City as some areas of the Steel Mill may be locked of for you if you haven’t completed the campaign
