Kaizo Mario Bros 3 Speedrun


Welcome to Kaizo Mario Bros 3, the most insane version of SMB3 ever!

Named after the infamous Kaizo Mario World Series, this 19 level version of the game was designed to be bananas. Modder  Obitus1 really went out of his way to make it as near-impossible as possible. But it is possible to beat. Watch as speedrunner mitchflowerpower annihilates it.
