Well aside from the fact that this game still looks amazing and still extremely fun to play, I thought I can do a better guide from the ones already posted online.

Like you guys, I've seen the Batman Arkham Video's guide to this annoyingly hard Riddler challenge. And like you, i just couldn't get the stars aligned perfectly like they did in their video, so after 10 million tries, I finally devised a reliable, RNG-free way to finish this god forsaken map.

@0:25 Silent Takedown the dude around the 2nd segment of the railing (first short segment)


@0:55 wait for the henchman to mention that the dude is out cold/not waking up before throwing the caltrops. MAKE SURE YOU THROW IT BEHIND HIS FOOT OR ELSE HE WOULDNT GET STUNNED

@01:06 make sure there are no dudes in the bridge before climbing up the ledge (the two guys in the screenshots are the one you need to watch out for. The step before this should make sure they're off the bridge already)

@01:10 you might not get the double ledge takedown prompt as quickly as I did here, but just shimmy along until you get the prompt


@01:40 perhaps the most RNG heavy part of this guide. Stay out of sight until Riddler comments on the dead guard. Wait until the jammer henchman (or the other armoured henchman) leaves to go check ♥♥♥♥ out before sprinting

@2:00 you may need to hit just one wall to get their attention. Try to do it quickly or they may be too far and not hear it. They'll say something if they hear it

@02:15 any henchman may come to the grate at this point. Try to get an armoured or jammer one in your takedown. After this, there's just 2 henchmen left and you can deal with them however you see fit. You might get shot a couple of times, but thats ok.

And that's it! Hope you guys find this helpful, even after 9 years since the game released lol
