Batman: Arkham City Riddler guide

STEEL MILL RIDDLER TROPHIES

STEEL MILL RIDDLER TROPHY #1

Grapple up to this ledge and use your explosive gel on the structural weakness.

STEEL MILL RIDDLER TROPHY #2

Use your line launcher or freeze blast to get across the water, then hack the console using your cryptographic sequencer.

STEEL MILL RIDDLER TROPHY #3

Throw a Batarang at this Riddler switch and the bars above it will lower. Use your line launcher to get over there, then crawl through the vent you see to find a trophy. 

STEEL MILL RIDDLER TROPHY #4

Notice the trophy behind bars. Use your Batclaw to open the hatch left of these bars, then pilot a remote Batarang to the north and look for an electricity arc over the water. Bring the electrified Batarang back through the hatch opening and into the fuse box.

STEEL MILL RIDDLER TROPHY #5

Use your freeze blast to create a raft in the water. Face east and you’ll notice a high point to which you can grapple. Find the trophy up there. 

STEEL MILL RIDDLER TROPHY #6

Float down the river on your raft toward the grinder on the left. Look up at the ceiling to spot this trophy. Use your Batarang to get it down as soon as you have a clear shot.

STEEL MILL RIDDLER TROPHY #7

Stand on the bridge to the north of this trophy’s location and use your Batclaw to remove the vent cover. Climb inside that vent to find a trophy. 

STEEL MILL RIDDLER TROPHY #8

Use your remote electrical charge on the nearby generator to move the cart. The trophy will then be revealed. 

STEEL MILL RIDDLER TROPHY #9

Crawl through the vent in the northwest room and use your grapple to get up to the high ledge you find on the other side. 

STEEL MILL RIDDLER TROPHY #10

This trophy is in the center of the room. You’ll need to do a running slide and pick up the trophy as you’re moving.

STEEL MILL RIDDLER TROPHY #11

Look for a hatch on the wall. Use your Batclaw to pull it open, then use your Batclaw again to grab the trophy. 

STEEL MILL RIDDLER TROPHY #12

If you enter the Assembly Line from the southernmost entrance on the west side, look up and to your left. There is a ledge above the vent that you can grapple too. Once you have, use your explosive gel to destroy the structural weakness.

STEEL MILL RIDDLER TROPHY #13

Step out into the main room and use your remote electrical charge on the generator. This will pull all of the carts towards the generator, revealing an opening. Use your freeze blast to stop the steam then crawl in to find your trophy.

STEEL MILL RIDDLER TROPHY #14

There is a vent cover in the same room as the generator used in #13. Pry it open and crawl through to find your next trophy. 

STEEL MILL RIDDLER TROPHY #15

Hack this console using your cryptographic sequencer to open the elevator door, granting access to the trophy. 

STEEL MILL RIDDLER TROPHY #16

Crawl under the floor grates and look for this pipe spewing steam. Close it off with your freeze blast, then climb past it to find a trophy.

STEEL MILL RIDDLER TROPHY #17

Use your remote electrical charge on the generator in this room, pushing and pulling the crane hook until it smashes into the fan on the back wall. Just beyond that fan you’ll find a trophy. 

STEEL MILL RIDDLER TROPHY #18

Navigate through the area under the floor grates and head south until you reach the spot where you first entered the steel mill near the start of the game. Look for a hatch that can be pulled open with the Batclaw.

STEEL MILL RIDDLER TROPHY #19

Continue through the vent you opened up during #17 and drop down into the hole you find. From there, use your line launcher to reach the riddler panel. Simply standing on it will open the trophy cage. 

STEEL MILL RIDDLER TROPHY #20

Just to the left of the freight elevators is a hatch that can be pulled open with your Batclaw. Do so to find a trophy. 

STEEL MILL RIDDLER TROPHY #21

At the bottom of the elevator shaft you’ll find a small hole that allows you to go even deeper. Drop in there to find a trophy. 

STEEL MILL RIDDLER TROPHY #22

Drop to the bottom of the freight elevator shaft and look up. Grapple to the point pictured above to find a trophy. 

STEEL MILL RIDDLER TROPHY #23

Use your explosive gel on the structural weakness to find a trophy.

STEEL MILL RIDDLER TROPHY #24

Use your quick Batarangs to destroy all the purple penguins. The trophy will then be revealed. Use your Batclaw to grab it. 

STEEL MILL CATWOMAN TROPHIES

STEEL MILL - CATWOMAN TROPHY # 1

On the underside of this bridge. Walk to the edge and climb down to reach the trophy. 

STEEL MILL - CATWOMAN TROPHY #2

This trophy is on the underside of one of the walkways in the smelting chamber. 

STEEL MILL - CATWOMAN TROPHY #3

Climb up the high section of this area of the map. There is a grate that you can crawl through - as seen above - to reach the trophy. 

STEEL MILL - CATWOMAN TROPHY #4

Provided you opened this elevator door as Batman using the cryptographic sequencer, you can just pick up the Catwoman trophy without issue. 

STEEL MILL - CATWOMAN TROPHY #5

In order to have access to this trophy, you need Batman to use the remote electrical charge on the generator in the loading bay to smash the crane hook through the fan on the south wall. This opens a path down to a pit of fire. As Catwoman you can pounce to the ceiling and crawl over the fence to reach a trophy.
