- Alternate weapon view
Equip the Batarang, Batclaw, or Multibatarang, then push LT to aim and RB to fire the weapon to get a behind-the-projectile view.

- 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.

- Easy 'Freeflow Perfection' achievement
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.

- Overcomeing 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, begin 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.

- Armored Batsuit
Successfully complete the game to unlock the Armored Batsuit in Challenge mode.

- Overcomeing 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.

- 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.

- Easy 'Mano-A-Mano' achievement
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 achievement. 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' achievement.

- 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.

- 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.

- 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.
