Batman: Arkham Asylum

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.

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.

Climb to the highest point of Arkham Mansion in Arkham East (the clock tower) and glide down for an easy Night Glider Trophy (Glide continuously for 100 meters).

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.

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.

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.

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.

After you've snapped a shot of 23 of the 24 of the Chronicle of Arkham markers, you'll need to track down the final marker. The key to solving the mystery of Arkham is the Warden, whom you last saw in the Security Control Room. Head to this room in the Penitentiary and enter the small central office area. Look on the floor for a circle of scribbles and etchings that say "BATMAN." Enter Detective Mode and take an Environmental scan of this to complete the final Chronicle of Arkham Riddle.
