About Hollow Knight

Developed and published by Team Cherry, Hollow Knight is a metroidvania action-platformer released on February 24, 2017, for PC, with Nintendo Switch, PlayStation 4, and Xbox One versions following in 2018. Players control a small nameless knight exploring Hallownest, a ruined underground kingdom populated by insects and consumed by a mysterious infection. The world is vast and largely non-linear, with interconnected areas that open up as players collect new abilities and find shortcuts between regions.

Combat is built around a nail, Hollow Knight's equivalent of a sword, alongside a spell system powered by Soul, a resource generated by landing hits on enemies. A Charm system lets players slot equippable items that modify healing speed, attack patterns, movement, and dozens of other variables, enabling a wide range of build options across a single playthrough. Boss fights are frequent, varied, and generally demanding, with a difficulty curve that rewards patience and pattern recognition rather than raw stats.

The game includes four free content packs released after launch, adding new bosses, story content, game modes, and the extensive Pantheons of the Gods endgame challenge. Hallownest itself is designed to reward exploration, with hidden areas, lore tablets, and optional encounters spread throughout its 40-plus hours of core content. Players who pursue completion can expect significantly more playtime.

Hollow Knight has sold over 15 million copies and holds a Metacritic score of 87 and an Overwhelmingly Positive overall Steam rating, making it one of the most celebrated indie games ever released on PC. Hollow Knight is not currently available on Xbox Game Pass. The game left the service in December 2025. Purchasing a key is the most straightforward way to access the game, with no subscription required and permanent ownership.
