Solving The Riddler’s “?”s

If you are perplexed by The Riddler’s more difficult 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). An easy 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 will solve the “Do you see what I see? No? Then maybe I am in a stronger position.” riddle. There are only a few of these riddles, but you must find both parts of the “?” and align them to solve the riddle.
“Solve The Spirit Of Arkham’s Mystery” chronicle

If you are skilled enough to find all of The Riddler’s secret maps, or if you find all the “Chronicle Of Arkham” hidden pieces 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. There will be some scribbling on the floor. Use your Environmental Analysis on it to unlock the final chronicle.
Easy combos

When fighting 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 increase your combo total.
Defeating Bane

Bane’s primary attack is similar to the trample done by the deformed Joker henchman. When Bane begins to run towards you, throw a Batarang at him, then dive out of the way. Bane will run into the wall and will be momentarily stunned. While he is stunned, start hitting him. Batman will then jump on top of Bane and rip off one of the hoses pumping him with venom. If your Batarang misses Bane, he will still run into the wall and appear to be stunned; however, he will just cover his face and try hitting you. When he turns around, run away from him. After you rip off the first hose, prisoners will jump from the railings and try to help Bane, and Bane will throw chunks of wall at you. You can focus on them or just try dodging them while focusing on Bane. Pull three hoses from Bane’s back to defeat him.
Defeating Poison Ivy’s plants

To destroy Poison Ivy’s large plants 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 enough time to produce the irritating orbs that can hurt you before you tear its heart out.
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 “125845712″ as the guard login number. You will login as Frank Boles and can read information about him.
Ras Al Ghul’s resurrection

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

In Intensive Treatment, there is a long hallway (where Scarecrow first attacks you) where you will hear a recording that 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.
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.
George Clooney reference

After rescuing Cash and the orderly from the Joker’s laughing gas, 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.” This is a reference to George Clooney, who once had the role of Batman.
Knightfall reference

If you lose to Bane, it shows a cutscene of him snapping Batman’s back over his knee. This is reference to Knightfall: Book 1, where Bane breaks Batman’s spine.
Scarecrow actor references

Listen to the first Scarecrow interview. You will hear him 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.

You’ve heard of Batman no doubt, but if you don’t read comics, it’s conceivable that you might be unfamiliar with Arkham Asylum. The iconic psychiatric hospital is essentially Gotham City’s Alcatraz, and it has housed just about every villain Batman has ever tangled with at one time or another. Now, thanks to Eidos and developer Rocksteady, Arkham is also the setting for a great third-person action game in which the lunatics take over the asylum and only you can stop them. As Batman, you not only get to go toe-to-toe with thugs in fast-paced punch-ups, but you also employ satisfying stealth tactics, play with great gadgets, solve some remarkable riddles, and do a decent amount of detective work. In short, you get to do all of the things that you want to when you don a Batman costume in a game, provided you weren’t hoping to get behind the wheel of the batmobile.

The combat in Arkham Asylum never gets overly complicated, though the number of moves and attacks at your disposal increases quite dramatically as you progress through the Story mode, earn experience points, and subsequently spend those points on acquiring new combo moves and gadgets. Throws, takedowns, and even batarang attacks can be incorporated into your combos this way, but you never need to press more than two buttons simultaneously, and the timing of your moves doesn’t have to be particularly precise. Fighting against mobs of up to a dozen enemies or so is a blast, and while they’re not smart enough to all just jump on you at once, they’re not stupid either. Given half a chance, thugs will pull pipes from walls to attack you with, pick up boxes to throw at you, and recover weapons from fallen colleagues. Fortunately, there’s one weapon that your foes seem blissfully unaware of but which Batman is incredibly comfortable with: the environment.
