Guaranteeing a Tiny Cartridge post, Yacht Club included a “Butt Mode” code, along with a few hundred other cheats, for Shovel Knight. If you enter “WSWWAEAW” as your name when starting the game, all mentions for a bunch of reocurring words (e.g. Shovel, Knight, Health, Magic) are replaced with “Butt.” Finally, video games have grown up.
I think these work with the 3DS/Wii U version, even though they were posted for the PC/Steam release? Much thanks to the dozens of readers who knew to immediately send this tip our way.
