The Proximity Detonation Explosive Gel upgrade is required. In Challenge mode, choose Rumble In The Jungle and fight through the first three rounds, conserving as much health as possible. In round 4, do not engage the Titan until everyone else in the room (other Arkham inmates) has been put down permanently. Do not use a Batarang -- if you hit the Titan with it at all, it voids the trophy. Quickly switch to your Explosive Gel and wait for the Titan to charge at you. Watch out since there is always a chance he will throw a dead body at you first. Dodge the charge, then set one of your own (meaning spray the floor with Explosive Gel; it is best to do it rightafter he rushes at you and make sure you let Batman completely spray the gel). Stand over the area you sprayed if possible. When the Titan charges again, evade and you should hear a loud bang. The explosion does not take much health off the beast at all, but it does not matter. After he takes one big blind haymaker punch move in, continue hammering him with attacks. You can build up a good twelve to fifteen hit combo on him before Batman delivers the knockout blow, earning, you the trophy.
Listen to the first Scarecrow interview to hear him talking and mention a Dr. Murphy, and a Dr. Combs will be mentioned by a security guard. Cillian Murphy played Scarecrow in the recent movies and Jeffrey Combs voiced Scarecrow on the later episodes of Batman: The Animated Series.
Rescue Cash and the orderly from the Joker's laughing gas, then stand in the main room looking at the smaller room where they were trapped. A ticker will scroll the following garbled message: "Dr. Clooney report to Gynecology.", a reference to George Clooney, who once had the role of Batman.
Enter the Warden's office and go to the back to the room with the Warden's portrait on the far wall. Turn left when you enter the doorway and approach the wooden wall. Destroy one of the wall panels with Explosive Gel and enter the opening to access an unmarked room with a blueprint on the wall. It displays the plans for the relocation of Arkham to Gotham City.
Bane's health meter has three sections. He will occasionally tear a chunk out of the wall out and throw it at you. Tap A twice to evade the throws. When he is about to charge, quick-throw a Batarang by tapping LT. Bane will cover his face and run head-first into the wall. After depleting one section of his health, run up to him while he is stunned and perform a combo. Batman will jump on his back and rip out a hose which supplies his venom. After each time that you do this, henchmen will jump the railings and attack you. Take out the henchmen while dodging Bane's attacks. Repeat this process three times to defeat Bane. Note: If you wait too long between attacks, Bane will recharge his health.
After Poison Ivy destroys the Batcave, cross to the three hills to land on the mainland at Arkham West. Then, go to the second one. There are two small holes through which you can see cliffs. Through one, you see the mainland which is directly in front of you after you land on the second hill. Before doing that, look and grapple over there then go to a small exterior. There will be a cliff which has no place to land. Glide onto that location and you will find a trophy which will unlock Record Breaker in Challenge mode.
Prior to the end fight with The Joker, The Joker sends thugs to attack Batman while he watches from a "throne" set on top of mannequins. In the graphic novel, Batman: The Killing Joke, when The Joker has Commissioner Gordon at the carnival, he is sitting on a "throne" atop skeletons.
After finding all of the "Chronicle or Arkham" hidden pieces or the Riddler's secret maps, there is one more blank chronicle left. Go back to where you found Clayface behind the wall in the penitentiary. Go upstairs where you left Warden Sharp. Notice the scribbling on the floor. Use Environmental Analysis to unlock it.
Note: This trick requires that Batman is fully upgraded with all combo-based upgrades, etc. This is easily done in the later rounds of the first Challenge, "Intensive Treatment". You must perform the following moves in a single combo, without getting hit, blocked, or allowing the combo counter run out: Quick Batarang (may be optional), Quick Batclaw (may be optional), Punch, Stun, Evade, Counter, Throw, Instant Takedown, Ground Takedown. Note: You can evade as many times as desired to maintain the combo. Start with the Batclaw and follow up with a Batarang. These may not be required, but you may as well throw them so they cannot hinder you. After using the first couple moves listed after those, plus a number of Punches to get your combo meter above 5x, you can perform a Throw. Do not let Batman hit anyone else or you may leave yourself without any opponents to continue the combo. Punch a bit more and Evade as needed, then use the Instant Takedown when becomes available. Before using a Ground Takedown to complete this combo, use some Batarangs to stun anyone else nearby. If it is all clear, execute the Ground Takedown to complete the "perfect" combo.
Where can I find the last spirit of Arkham?
It's not listed on the riddler's challenges. I read that I need to find who the spirit of arkham is. Who is it?
Answer from RaiderOfTombs
Search the Central control room (the last place you see the warden). You will see a smaller round room lined with computers on desks. There is also some writing on the ground. Just scan that room and you've found it.
