Spoiler for How the Penguin fight works:

Actually The Penguin will stop shooting all-together once you reach the arc with the ramp, and he'll mock Batman saying "I'll let you have this one". So move slowly towards him with the disruptor ready, cause if you get TOO close he'll fire at you again. You don't have to be as close as you think for it to work.

And yes, the ending was an incredible shock...

Spoiler for ENDING SPOILERS:

R.I.P. The Joker. You were the one homicidal psychopath that nobody ever wanted to see go.
