Additional Updates: Switch 2 Edition and PC Enhancements
Team Cherry simultaneously announced an enhanced version of the original Hollow Knight for Nintendo Switch 2. The updated edition incorporates high frame-rate modes, higher resolutions, and advanced graphical effects matching Silksong‘s visual quality standards.
Nintendo Switch owners can upgrade to the Switch 2 Edition free when it launches in 2026. PC players already benefited from updates including 16:10 and 21:9 aspect ratio support for Steam Deck and ultrawide monitors. The studio continues refining all versions across Steam, GOG, Nintendo Switch, PlayStation, and Xbox platforms.
Fan Community Celebrates the Announcement
The gaming community erupted with excitement across social media, Discord servers, and Reddit communities. Hollow Knight subreddits flooded with fan art, speculation about nautical mysteries, and theories about the new bosses’ identities. Many players praised Team Cherry for their commitment to free content updates.
Merchandise makers capitalized on the momentum. Team Cherry partnered with artist Alex Colvin and merchandise specialist Fangamer to release collectible mini figurines depicting Hornet and character rivals. Pre-orders for individual figures and complete sets opened immediately following the announcement.
What Does This Achievement Mean for Independent Gaming?
Silksong‘s 7 million sales demonstrate that indie games can achieve mainstream commercial success without massive marketing budgets. The metroidvania’s success validates the value of quality craftsmanship, meticulous design, and fan respect over aggressive monetization tactics.
Team Cherry charges just $19.99 for the base game while promising free major expansions. This player-first philosophy stands in stark contrast to industry trends toward paid DLC and battle passes. The team’s small size makes the achievement even more remarkable, proving that three core developers can produce world-class experiences valued by millions.
Industry Implications
Publishers now recognize that respecting players and delivering genuine value builds lasting franchises. Silksong surpassed competitors with triple the development budgets, signaling a shift toward authenticity and substance in gaming culture.
“Watching the community grow, seeing the amazing art, the mods, the unexpected strategies, and the support between players through the game’s challenges has been hugely rewarding for us here at home.”
