Hollow Knight, the beautifully hand-drawn Metroidvania that was released early last year on PC platforms, is making its console debut on Nintendo Switch today, Nintendo announced during its E3 streaming press conference. The Nintendo Switch release includes “the new items, areas, characters and bosses from the currently released content packs.”

After a successful Kickstarter campaign in 2014, Hollow Knight was released to wide acclaim in February 2017. Since then, the developers have released four free content packs, adding everything from new quests, characters, boss fights, music and more. Those four packs — Hidden Dreams, The Grimm Troupe, Gods & Glory, and Lifeblood — are a part of the Nintendo Switch version of the game.
