It's been almost five years since Cuphead launched. Along with that 2018 debut, Studio MDHR announced "The Delicious Last Course" expansion with a planned release in 2019. It's taken a while for the downloadable content to be ready, but now the studio is prepared to give a release date. The DLC is coming on June 30, 2022.
Studio MDHR even shared a new trailer during The Game Awards showing the run-and-gun platformer's gorgeous 1930s art style. The Delicious Last Course takes place on an unknown island called Inkwell Isle. There will be new weapons and charms that you can use when battling bosses in the game. Ms. Chalice is also joining Cuphead and Mugman in this new adventure.
