How to Get the 'Contract Terminated' Achievement in Batman: Arkham City

Deadshot is one of my all-time favorite Batman villains. So when I saw that he was in Batman: Arkham City, I jumped on this sidequest faster than I jump on a fresh batch of cornbread. Don't judge me, I'm from Indiana.

To get the 'Contract Terminated' achievement, you have to complete the sidequest Shot in the Dark. A political prisoner will contact you and ask to meet you on a rooftop where he'll proceed to spill his guts. Before he can get too much out, though, he's assassinated by Deadshot. The rest of the quest is pretty straight forward, but it's totally awesome. If you get stuck, check out the video below for a great walkthrough.
