No you have to be above the enemy. It's sort of tricky to set up but you want an enemy to walk right under a ledge while you are perched on it. Batman will swing down and wrap his legs around the guy's neck to choke him out. A lot of ledges aren't quite right to do it which is why you haven't been able to get it to trigger.
yup this can be easily done in the bank Bank is the only place that i found to fit all the criteria.
any idea, if all completed challenges carry through to Night mode like New game +, 'cause I think that's my only hope now.
actually its doable in I am the night mode your challenge can be done after joker reveal predatory map (Bank)
here is a list of predator situation in the campaign in order: GCPD (useless for Rank 6), Bank(Rank 6), Steel Mill(Rank 7 Beatdown challenge or more), Hotel Lobby, Top of Hotel, Under the Bridge, Blackgate. sidequests predator: Church (after Black Mask Most Wanted), Deadshot Bank(final Rank can me done easily here)
make sure you copy your save file because if you accidentally finish predator and didn't get the challenge then you lose a predator map opportunity. Also try to complete multiple challenges in one take (remember challenges cannot be skipped and should be done sequentially) Also the enemies are the same difficulty as NG+ mode but keep restarting checkpoint and its very doable. and always mind your health.
any ideal place to do this. I am at Royal Hotel 40th floor and think I'm running out of predator rooms.
After the hotel? I really don't know. The bank is the best map to do that one as well.
I tried here for an hour, just couldn't manage to trigger ledge takedown.
Why don't they give us patch that re spawns enemies
Okay, it's hard to describe, but... you have the two upper paths on either side, yeah? And you see how just below them towards the center are those yellow-y grate things with windows? Stand atop those. And when a thug walks by those, you can do a hanging ledge takedown.
