This is a tool-assisted speedrun. For more information, see http://tasvideos.org/4300M.html. TAS originally published on 2020-10-09.
The hero of Gotham City goes against the villain of Gotham City. His fists are more powerful than any weapon in the world, but he rarely kills anyone. It's not like his enemies can hurt him anyway. After all, he's the hero, and heroes are supposed to be invincible.
DreamYao's first publication to the site improves on a venerable record, beating the previous movie (http://tasvideos.org/1049M.html) by 1.26 (76 Frames @60.1 FPS) seconds.
Enjoy the movie, and the excellent soundtrack and graphics of this game.
