That's exactly what I did. Then after that I detonated the Snap-Flash and performed a beatdown on the sniper in the tower/window.
Anyways, once again, thanks for the videos. It definitely helped me for some of the bothersome Predator challenges that involved Explosive Gel (Natural Selection, Police Brutality). I probably would've never figured out how to efficiently plant the Explosive Gel in the appropriate places and detonate it at the correct time.
My last achievement for this game now is Story Teller.
Note: I had lots of trouble with Meltdown Mayhem (Extreme). I have absolutely no idea why. Everytime I followed your method in the video something terrible happened. Performing a double-ledge-takedown was the challenge holding me back; it's tough to perform it when it's a very small map and there is almost always an enemy on the ground that spots you.
