- 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.

- Easy 'Freeflow Perfection' trophy
Notice: This trick requires that Batman is fully upgraded with all combo-based upgrades. You can do this fairly easily in the later rounds of the 'Intensive Treatment' challenge. You must be able to perform the following moves in a single combo, without getting hit, blocked, or allowing the combo counter to run out: Quick Batarang (may be optional), Quick Batclaw (may be optional), Punch, Stun, Evade, Counter, Throw, Instant Takedown, Ground Takedown. Notice: You can evade as many times as desired to keep the combo going. Begin with the Batclaw followed by a Batarang. These may not be required, but there is no reason not to use them. After using the first few moves listed after those, plus a few 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 it 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.

- 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 activate 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.

- Easy 'Mano-A-Mano' trophy
This trick requires the Proximity Detonation Explosive Gel upgrade. In Challenge mode, select 'Rumble In The Jungle'. Make it 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 (Arkham inmates) have been defeated. Do not use a Batarang -- if you hit the Titan with it at all you will not get the trophy. Immediately switch to your Explosive Gel, and wait for the Titan to charge at you. Be careful because there is always a chance he will throw a dead body at you first. Dodge the charge, then set one of your own (spray the floor with Explosive Gel; it is best to do it immediately after he rushes at you, and make sure you let Batman completely spray the gel). If possible, stand over the area you sprayed. When the Titan charges again, dodge, and the Explosive Gel should detonate. The explosion does not take much health off the Titan, but it does not matter. After he takes a big blind haymaker punch, attack him. You can build up a twelve to fifteen hit combo on him before Batman delivers the knockout blow earning you the 'Mano-A-Mano' trophy.
