Batman: Gotham Knights

You push down the accelerator and the Batmobile speeds forward from out of the darkness. Before they can react, the thugs are splattered on the pavement. There's no one else there, so you head home.

A day later, you go to see Commisioner Gordon about more Joker leads, but you're ultimately placed under arrest. There were cameras at that street corner, and you've committed murder in plain sight of them.

You're unmasked and thrown in prison. Alfred is killed by your enemies and your fortune is seized by the government.

Finally, you're sent to Blackgate... where you're killed in a prison riot.
