A new glitch has been discovered in the classic NES and Famicom game Super Mario Bros. that grants players infinite lives.
The glitch requires players to use the game's two player mode and to have already beaten the game once. According to RetroCollect, the process is a little complicated.
"First, you must first take player one's Mario to the second level of the game and throw away your first life," the description reads. "With Luigi taking over, player two must traverse all the way to World 5-2 and find the hidden beanstalk block halfway through the stage. Once there, Luigi must start climbing the vines, however, he must await —and take on the chin — an incoming projectile from one of the Hammer Bros. Upon being hit, once player one resumes control of Mario, the beanstalk from World 5-2 will start growing in World 1-2, providing all you need to infinitely kick shells for unlimited bonuses."
Watch the video above to see how it's done. Although a little more technical, the glitch is similar to "Turtle Tipping," in which players can time their jumps to land on a turtle shell over and over for easy lives.
Super Mario Bros., the first game in the iconic series, was released in 1985.
