It was indeed the finale. I fought the henchmen in the hallway, I fought the two titans in the main room, and then I was worried that Joker was going to be a boring boss battle of just another titan charging around the room. Oh no. The last parts on the rooftop were tricky, and I had to restart twice before I finally defeated him, with a sliver of health left.
Overall, this has been a great game. I'm not really interested in the whole superhero universe, but this game took the established characters and made them into something really interesting. The setting is pretty creepy at times, and it felt a very solid world (even if the rationale for the batcave was a bit flimsy). It wasn't too long, but if I wanted to get more out of it there's a number of extra modes which I've not touched, plus the main game on a hard difficulty level. For now, though, I'm done.
