How Melty uses Hollow Knight

Hallownest movement and bosses used as one half of a two-game mashup.

Hollow Knight is a Metroidvania title. Melty is not a storefront for it. The app looks for a copy you already own, then installs mashup files and starts the game when you press Play.

Mashup URLs that mention Hollow Knight include Hollow Knight + Portal, Hollow Knight + Skyrim, Hollow Knight + Elden Ring.

Setup, safety, friends

Play downloads the mashup, installs what it needs, and launches. Uninstall restores the files Melty touched.

Multiplayer mashups mint an invite link. Uploads are checked for dangerous files.

FAQ

Does Melty include Hollow Knight?

No. You need your own copy. Melty opens the store if Hollow Knight is missing.

Can I mash Hollow Knight with another game I own?

Yes. Melty's product line is "combine any game in your library and play with your friends."

What is a mashup?

A mod that joins games into one. In SkyCraft, you play Skyrim as a Minecraft player.

Do I need the games?

Yes. Mashups run on games you own. If you are missing one, Melty sends you to its store.

What does Play do?

It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.
