Any way to hack worst nightmare?

[T_BONe]

I finished both story mode and story mode + and Im stuck at Worst Nightmare challenge 10. The one that unlocks sonic batarang takedown. I need it to earn a medal in challenges. My problem is that even tho I can find locations with HIGH threat in Gotham the game for some inexplicable reason tells me I cleared a predator situation with HIGH threat but does not unlock the upgrade ( those places contain snipers and large groups of armed enemies). I am the night is not an option for me as I wont risk getting as far in the game without backup. So thats basically my only issue with the game. Frankly, I think this way of unlocking gadgets and restricting them only to story mode sucks but whatever...
Suggestions are welcome.

Took me ages to get this one.
It is the high threat without being spotted or something, right?
You know how I eventually got it? After a brawl against unarmed goons.
It's very glitched. Outside predator encounters don't count anyway, only indoor encounters.
My suggestion would be to try I am the night mode for a while until you get it.
The ones after that one aren't so bad, except the one to take down 3 people with 1 fuel tank. And even that is easy once you know how to do it. Just use the remote claw to pull 2 guys together close to the tank. When another guy walks close, knock them over by pulling the original 2 together again. When they are down pull the tank to the guy still standing. The 2 on the floor will be taken out, and the guy standing will take the brunt of the explosion and will go down as well.
Takes some time lining it up just right, but it's not too difficult.
The one you are at now is the one I had the most trouble with. And like I said, it was a combat encounter that gave it to me in the end, for some reason


And don't worry about I am the night mode. All it does is delete your save if you die. Just quickly reload last checkpoint if your health gets low

What do you mean you won't risk getting as far in the game without backup? If you die in IATN you only have to restart IATN. The dark knight challenges you complete are saved regardless.

Some of hte ranks you can't do in the city such as steal mill entrance and roof of GCPD, you have to be inside a building...

I did 9 and 10 at the same time in the big predator room in the Hotel right before the first bane fight. 9 was the four loud takedowns (grate, ledge, inverted, and quick loud takedown from behind). Did those first. And as long as you are not seen during those 4 as well as the rest of the room you get 10 too.

I did most of them in I Am The Night mode since I didn't bother to even look at challenges until after I beat the game twice.
