4I. Part Nine - Never Fear =

Arkham Island - Arkham East: Approach plant pods and press X to rip out their cores. Dodge spores or use Batarangs if they fire them. Watch out for enemies. Head towards the mansion entrance and use the vent above it.

Joker Teeth: Two are located near the door to the Abandoned Tunnel.

Arkham Mansion - Mansion Entrance Hall: The floor is unsafe. Use the line to climb through the vents.

Main Hall: Head right, drop to the walkway, go north, then west, then north again to leap to the stairs. Talk to Cash for directions to Killer Croc's lair. Grapple back to the walkway and exit the way you came.

Mansion Entrance Hall: Exit the area.

Arkham Island - Arkham East: As you proceed north, you will encounter eight goons.

Arkham North: A sniper is located high on the south wall near a door. Sneak to a guard tower, climb to the top, and launch yourself at the sniper. Avoid the plants. Enter the door once the sniper is dealt with.

Joker Teeth: Three are found near the sniper's location.

Riddler Trophy: Climb the western guard tower and look west. Line across to reach it.

Intensive Treatment - Maintenance Access: Your objective is the vent on the north wall. Use vents and climbing to reach it. Continue through the vents to the end.

Riddler Trophy: Located in the northeast corner, accessible via climbing and vent crawling.

Intensive Treatment Lobby: You will face seven armed enemies. Be cautious of the explosive gargoyles; you can use them briefly. Take out the first enemy by waiting for them to turn. Drop to the lowest floor to deal with a patrolling enemy. Use Sonic Batarangs and Gel traps to isolate and defeat the remaining five. After clearing the room, go to the offices and disable the booby-trapped box to open electric fields.

Cell Block Transfer: This section is a brief narrative interlude.

Nightmare: Head up the ramp and line across the long gap when the moving wall is away. Scarecrow will appear. Hide behind equipment, then move to the hallway to face skeletons. Continue climbing and avoiding hazards. Follow a moving wall for cover, then grapple between elevators, avoiding Scarecrow's gaze. Near the Bat-signal, hide behind the wall to its right. You will then fight three waves of skeletons: normal, a Titan skeleton (easily defeated by crashing it into a wall), and a final wave with both normal and Titan skeletons.

Cell Block Transfer: Your objective is to the north.

Riddle: Head east by exiting south and re-entering through another door. Hack the security box in the southeast corner, go to the office, and examine the picture on the desk.

Interview Tape: Hack the security box in the northeast corner. Requires the Range Amplifier.

Security Transit: Your objective is at the bottom where Scarecrow went.

Interview Tape: Accessible in the offices after an electric field is deactivated.

Chronicle of Arkham: About halfway down the shaft, after an upper shimmy ledge, crouch through an area with a vent cover leading to two weak walls. Blow up the left wall.

Riddler Trophy: Before a large gap not far from the lower floor, climb up from a ledge to a small side-area with a suspended vent cover. Remove it.

Riddle: At the bottom of the elevator shaft, take a vent leading between the two shafts to a room with straw on the ground and plans on the walls.

Bottom of Shaft: Defeat an armed guard and two unarmed guards (one with knives). Hack the bomb to access the lower floor. Deal with six more unarmed guards and gun cabinets.

Secrets Map: Found in the office on the bottom floor.
