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.

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.

"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.

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

Scarecrow Actor References
