Princess Peach has been captured again by Bowser, but this time he has sealed her and the Toads away in the Land of Memes - a sick, twisted, meme-filled version of the Mushroom Kingdom created by Bowser's black magic. Not only that, but they've vandalized the inside of the castle with stupid memes all over the walls! Mario is too busy Smashing and golfing, so it's up to Luigi to save the day!

Luigi! The mean green mustache machine is the main character of this game, with a model made by Cjes and voice clips taken from New Super Mario Bros., Mario Kart 64, and the Mario and Luigi series! He jumps higher than Mario, swims faster, and has the special triple jump right from the get-go! He runs out of oxygen faster and is a bit more slippery to control than Mario, however.

New textures! Because the Land of Memes is so, well, meme-filled, the textures should represent that! How about jumping on a Goomba from the so-bad-it's-good YouTube video "Mario Pissing?" Or how about smashing a Whomp with a fetish for flattening people? Or even getting chased around by a Boo with Dio from JoJo's Bizarre Adventure's face?

New music! The music of Luigi's Meme Mayhem is taken from other games - not only from the Mario series - such as Undertale, Sonic, and Bomberman. There is a list of people whom the .M64 files are credited to in the zipped folder.
