[#2] A case of mistaken identity?

Location: Security Control Room (Penitentiary)

Look around before you head up to the control booth. A shapeshifter can be found behind a glass wall (he'll turn into different people). Scan him and you'll solve the riddle.

[#3] The room is the end of days for even the most celebrated killer.

Location: Main Cell Block (Penitentiary)

Proceed to the western cell block and scan the cell filled with calendars.

[#4] Two people, one voice, no gun?

Location: Main Cell Block (Penitentiary)

Search the upper control room and find a Tommy Gun on a display.

[#5] What has four walls, two sides, and one ex-DA?

Location: Controlled Access (Penitentiary)

Explore all the nearby cells and be on a look out for a poster. Scan it to solve this riddle.

[#6] All alone in your cell? Why don't you break the ice with the most dangerous prisoners?

Location: Extreme Incarceration (Penitentiary)

Defeat all the inmates and scan the icy cage found nearby.

[#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.
