Batman: Arkham City - Riddler's Revenge [Linux w/Proton] Predator Map - Meltdown Mayhem {3 Medals}

Other than the first challenge here, the rest of this map is pretty easy. Even the first one isn't bad, but it probably helps if the target is by himself when you drop smoke on him. I'm not sure why Batman would only have one pellet, but that's how the game goes.
