During the final confrontation with Scarecrow, it shows Batman's gravestone, which is the same design as the current comic book series BatMan RIP.
- Defeating Bane
Bane's primary attack is the similar to the trample done by the deformed Joker henchman. When Bane starts to run toward you, throw a Batarang at his head then dive out of the way. Bane will run into the wall and will be momentarily stunned. While he is stunned, run up to him and throw some punches at him. Batman will then jump on top of Bane and rip one of the hoses pumping with Venom. If your Batarang misses Bane, he will still run into the wall and appear to be stunned, but this is a trick. He will cover his face and try to hit you. When he turns around, run away from him. After ou rip off the first hose, prisoners will jump from the railings and try to help Bane. Focus on them while watching on Bane. Bane will throw chunks of wall at you. Keep repeating this until Bane has been defeated.
- 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 Mano-a-mano trophy
This strategy requires the Proximity Detonation Explosive Gel Upgrade. In Challenge mode, select Rumble In The Jungle. Fight 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 (other Arkham inmates) has been put down permanently. Do not use a Batarang -- if you hit the Titan with it at all it voids the trophy. Immediately switch to your Explosive Gel and wait for the Titan to charge at you. Watch out because there is always a chance he will throw a dead body at you first. Dodge the charge, then set one of your own (meaning 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). Stand over the area you sprayed if possible. When the Titan charges again, dodge and you should hear a loud bang. The explosion does not take much health off the beast at all, but it does not matter. After he takes one big blind haymaker punch move in, just keep hammering him with attacks. You can build up a good twelve to fifteen hit combo on him before Batman delivers the knockout blow earning, you the trophy.
