The Joker gets pwned by Captain MacTavish.
The Joker was chasing after the Swat Truck Harvey Dent was being kept in. There were no wingmen left, even the Batmobile had been wrecked. The two officers in the SWAT truck were becoming more and more worried. All of a sudden, Captain MacTavish, and that other nub, Roach, or whatever his real name is, came out of nowhere on the Batcycle.
Six Minutes Before…..
Captain MacTavish and his Sidekick, Robin…. I mean Roach, are back from their latest mission. They are going to be guest stars on Gotham City's hit comedy show, Friday Night Live. On their way, they saw Harvey Dent on the T.V, then decided to protect him on the way to the jail.
They followed the Batmobile until it crashed, then MacTavish stopped to help him.
"Stop the Joker", Batman said, before he passed out and Alfred had to carry him home.
So the two soldiers had to pop open the Batcycle and get on it, like with the snowmobile in the demo. It was time to kick some Bad Guy butt.
Six Minutes Later…..
The Batcycle roared behind Joker's truck, gaining on it with each second.
MacTavish's sidekick, Roach pulled the cycle parallel with the 18-Wheeler, and took out the henchmen with his Glock 18, before MacTavish jumped into the open truck, knife at the ready.
The Joker lunged at him from the corner, but MacTavish pressed in Right Stick at the right time, ripping off the Joker's head, and saving the day.
Just to be safe, they put C4 on the truck and walked away slowly, with an explosion in the background.
