Batman Arkham Asylum [Nocturnal Hunter] Predator Challenge Walkthrough (1:13.39)

Excellent DLC to hone your skills to become a good predator, this requires a bit more thought as this is a much bigger map compared to the other predator maps. I provide a realistic simulation on how to complete this challenge with both speed and no damage taken. Played on PC with mouse and keyboard. Final Time: 1 minute 13.39 seconds. What Goes Up - When a henchman climbs to the top of a ladder, send him flying back down. Last Man Standing - Take down the high security henchman (in red) last. Smash and Grab - Perform an Inverted Takedown from a vantage point through the glass ceiling (Upgrade required). Run towards the corner and proceed to grapple on top of a gargoyle right above the platform above you. Look left and wait until the henchman puts one foot on the staircase and the batarang him to send him rolling down the stairs. Whilst he is falling grapple to the gargoyle above him and jump down and put some Explosive Gel next to the ladder and proceed to take down the henchman who is now at the bottom of the stairs with a ground pound. Grapple onto the gargoyle left when facing the opposite room and glide down to the henchman on the left walkway and take him out with a Silent Takedown. Then grapple onto the gargoyle which has the glass ceiling below and wait for a henchman to pass under perform the Inverted Takedown achieving "Smash and Grab". Whilst in action a henchman will have climbed up the ladder but the Auto Proximity Detonation of the Explosive Gel sprayed earlier will detonate and send him flying back down taking him out getting "What Goes Up". Look left and you will see a lone henchman on the top walkway near the stairs in which the first henchman fell down, batarang him and go to him and take him out with a ground pound. Isolate the high security henchman in red and leave him to last. Take out the other two henchmen with batarangs followed by ground pounds, Batclaw off the ledge, Sonic Shock Batarang or Silent Takedowns. Then proceed to take out the high security henchman last to get "Last Man Standing". Very well made map with similar henchmen reactions every time it is attempted so this is a good method which also gives a decent time. Just remember to be able to isolate the high security henchman as that may be the hardest goal of the challenge. Hope this useful in getting your challenge complete!
