Sky High

Sky High is a Predator A.R challenge map in Batman: Arkham Knight. It is located inside the Stagg airships, and enemies consist of multiple default soldiers, three medics one Optically Camouflaged enemy and one Minigunner. It is a part of the "Crimefighter challenge map pack #2".

The default character is Robin.

 * Stun all the medics at the same time.

Tips

 * Despite the fact that one of the challenges say "stun", there's no penalty in using Snap-Flashes on the three medics, and detonating them at the same time. They will be knocked out, but in most cases the medal will be unlocked.

Trivia

 * Despite the default character being Robin, terrified enemies might still say something along the lines of "Just you and me Bat". This is most likely an oversight, as every other Batman-related line is disabled when playing as an another character. This is extremely rare, however.
 * After 1.09 update, grappling to a vantage point from under the floor sent the player to the walkway on the middle of a room, which could lead to detection. This was fixed on the November/1.11 update.
