BatMan RIP reference

During the final confrontation with Scarecrow, it shows Batman's gravestone, which is the same design as the current comic book series BatMan RIP.

Defeating Bane

Bane's primary attack is the similar to the trample done by the deformed Joker henchman. When Bane starts to run toward you, throw a Batarang at his head then dive out of the way. Bane will run into the wall and will be momentarily stunned. While he is stunned, run up to him and throw some punches at him. Batman will then jump on top of Bane and rip one of the hoses pumping with Venom. If your Batarang misses Bane, he will still run into the wall and appear to be stunned, but this is a trick. He will cover his face and try to hit you. When he turns around, run away from him. After ou rip off the first hose, prisoners will jump from the railings and try to help Bane. Focus on them while watching on Bane. Bane will throw chunks of wall at you. Keep repeating this until Bane has been defeated.

Easy combo total

Fight a Titan henchman along with a group of normal henchmen. Stun the Titan, then jump on his back and use him to hit the normal henchman to build your combo total.

Easy Night Glider achievement

Reach the highest point of Arkham Mansion in Arkham East (the clock tower), then glide down.

Frank Boles information

There is an advertisement in the Medical Facility for the hospital's website (www.ArkhamCare.com). You can visit this URL in a web browser and use the employee login section. Enter the guard login number of "125845712". You will login as Frank Boles and can read information about him.

Hidden website

In the Intensive Treatment, there is a long hallway (where Scarecrow first attacks you). A recording talks about how to treat patients. It tells you that you can find pricing information at http://www.arkhamcare.com/prices/ which is a real website.

Killing Poison Ivy's plants

To kill Poison Ivy's big fat plants that sit on the ground, get near them to pull out the heart by dropping from above. Find a high point such as a tower or building then drop down directly beside it. The plant will not have time to produce the irritating orbs that can hurt you before you rip its heart out.

KnightFall reference

If you lose to Bane there is a cinematic of him snapping Batman's back over his knee. This is reference to KnightFall book 1, where Bane breaks Batman's spine.

Ras Al Ghul's resurrection

You can find Ras' corpse in Dr. Young's office. Later in the game if you re-visit the office, Ras Al Ghul's body bag has been unzipped and his body is missing, showing that he once again resurrected and escaped.

Scarecrow actor references

Listen to the first Scarecrow interview. You will 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 newer movies and Jeffrey Combs voiced Scarecrow on the later episodes of Batman: The Animated Series.

Solve The Spirit of Arkham's Mystery chronicle

If you are skilled enough to find all of The Riddler's secrets maps, or if you can actually find all the Chronicle of Arkham pieces hidden throughout the game without them, there will be one more blank chronicle remaining to decipher. To unlock it, go all the way back to where you found Clayface behind the wall in the penitentiary. Go up the center stairs where you left Warden Sharp a long time ago, and there will be some scribbling on the floor. Use your Environmental Analysis on it and the last chronicle will unlock.

Solving The Riddler's "?"s

If you are stumped by The Riddler's more "taxing" riddles such as "What's right in front of you but still hidden from view?", you will usually be able to use Detective mode to find a piece of a question mark without a dot (or the dot without the question mark). The easiest way to see an example of this is to go to the second balcony outside of the penitentiary. Look toward the medical facility and enable Detective mode. You will see a "?" with no dot under it on the floor. Grapple to the balcony above and on the center pole of the railing is the "?"'s dot. Align them onscreen and use Environmental Analysis. This solves the "Do you see what I see? No? Then maybe I am in a stronger position." riddle. There are a only a few of these, but remember you must find both parts of the "?" and align them to solve the riddle.
