Some sinister-looking man is stalking your every move, watching you from the rooftops of Arkham City like a murderous hawk. So why not walk up and say hi? The Watcher in the Wings side mission involves you finding this mysterious figure in four separate locations, all of which are unknown to the almighty Batcomputer. Fortunately, our technology exceeds that of the world’s greatest detective.
As soon as Batman completes his first story mission involving Catwoman, you may spot the watcher up on the roof just south of the courthouse. Approach him and he’ll vanish, leaving a symbol behind. Scan that symbol to complete part one of this side mission.
In the eastern part of the Industrial District there’s a ferris wheel. The watcher is waiting at the very top. Again, approach him and scan the symbol after he leaves. You’ll need to have finished the steel mill for the first time before the watcher will appear at this location. If you’ve already done that, and the watcher is still absent, try quitting and reloading the game.
Look on the roof the building northeast of the entrance to the subway. It’s one of the tallest buildings in the Bowery, so it’s not hard to find. You’ll need to have already interrogated Quincy Sharp before the watcher appears at this location. If you’ve done that, and the watcher is still absent, try quitting and reloading the game.
Check the roof of the building just west of GCPD. You’ll need to have already rescued Vicky Vale before the watcher appears in this location. If you’ve done that, and the watcher is still absent, try quitting and reloading the game.
The final sigil
Scanning the fourth symbol that the watcher leaves behind will automatically take you to the Batcomputer screen. Use the right and left sticks to rotate and move the sigil so that its four points match the four locations in which you spotted the watcher. Doing so reveals the watchers final location: the eastern side of the church. Scan the symbol on the wall there to complete this side mission.
