This is a tool-assisted speedrun. For more information, see https://tasvideos.org/3119M TAS originally published on 2016-04-11 Kaizo Mario Bros. 3 is a ROM hack created by the late Obitus1 designed to challenge the most skilled Super Mario Bros. 3 players, just like the Kaizo Mario World games are designed to challenge the most skilled SMW players (we have a published run of the third iteration right here ( https://tasvideos.org/2317M )). Naturally, Lord Tom ( https://tasvideos.org/Users/Profile/Lord%20Tom ) forgoes most of the challenges proposed in this hack and showcases some interesting strategies for beating the 22 levels in record time. -------- The official encodes feature commentary by the author as soft subtitles.
