[#7] Prometheus, Arkham guards' most wanted and most hated.
Location: Guard Room (Penitentiary)
Requirements: Explosive Gel, Ultra Batclaw, Line Launcher
Start off by moving to your left. It shouldn't take long until you'll have a chance to use your hook in order to grapple up to an upper ledge (screenshot #1). Use the Explosive Gel to blow up a wall found to your right. Make sure that you're standing in front of a newly created opening (screenshot #2) and use the Ultra Batclaw to rip off a new wall seen in the distance. You can then use the Line Launcher to get to the other side safely (screenshot #3). Choose the Batarang from your inventory and use it to destroy a control panel found to your left (screenshot #4). Doing this will activate large fans and effectively dispose of the toxins. Drop down to a previously inaccessible area of the Guard Room. Go to the north-east (screenshot #5) and scan a small poster found on a wall.

[#8] When is something right in front of you but still hidden from view?
Location: Guard Room (Penitentiary)
Requirements: Explosive Gel, Ultra Batclaw, Line Launcher
Start off by moving to your left. It shouldn't take long until you'll have a chance to use your hook in order to grapple up to an upper ledge (screenshot #1). Use the Explosive Gel to blow up a wall found to your right. Make sure that you're standing in front of a newly created opening (screenshot #2) and use the Ultra Batclaw to rip off a new wall seen in the distance. You can then use the Line Launcher to get to the other side safely (screenshot #3). You must now turn around so you'll be facing the southern wall where you blew up the wall. Zoom in on the question mark and scan the whole thing.
