Not out of the box — but the SSMP (Silksong Multiplayer) mod makes it co-op and PvP. Hollow Knight: Silksong is a co-op platformer game released in 2025, not enough Steam reviews yet. $19.99 on Steam.
Early multiplayer for Silksong with lobbies, co-op and PvP. Moving fast — versions must match. Steam lists Hollow Knight: Silksong as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
