Hollow Knight: Silksong is already a huge hit on Steam despite causing Valve’s storefront to crash, posting massive concurrent player numbers.

At the time of this article’s publication, and as those storefront problems ease, Silksong was on a huge 453,993 concurrent players on Steam, making it the third most-played game on Valve’s platform behind only Counter-Strike 2 and Dota 2.

This number looks set to rise, too, as more people download the game ahead of its first weekend on sale. The question now is, just how big will it be? It’s already the 29th most-played game on Steam of all-time, with the likes of Helldivers 2 in its sights.

Silksong is one of the most anticipated games of 2025. Over six years after its initial announcement and as the most wishlisted game on Steam, Silksong finally launched today, September 4, across PC, Nintendo Switch, Nintendo Switch 2, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X and S priced $19.99 and weighing in at 7.62GB.

Of course, Silksong’s true player count will be much bigger across all platforms. Neither Sony, Nintendo nor Microsoft make player numbers public, but Silksong crashed those storefronts, too, so it will be massive everywhere. And let’s remember Silksong is a day-one Game Pass title. Yep, this one’s enormous, perhaps even the biggest indie game launch of all time.
