What "Portal 2 + Hollow Knight" means here
This is the indexable page for "Portal 2 plus Hollow Knight mashup" and "Portal 2 Hollow Knight crossover". The homepage does not add a visual tab for every pair.
Melty does not need a celebrity mashup name for this query. Portal 2 + Hollow Knight is two owned games and one Play button.
Portal 2 is puzzle. Hollow Knight is Metroidvania. Melty starts the mashup on Windows. Uninstall restores files. Multiplayer mashups mint an invite link.
Play, friends, AI
Press Play. Melty downloads the mashup, installs files, and starts the host. Uninstall puts Portal 2 / Hollow Knight files back.
Want a custom Portal 2 + Hollow Knight? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

FAQ
Can Melty mash Portal 2 and Hollow Knight?
Yes, if you own Portal 2 and Hollow Knight. Melty is an AI game masher / one-click launcher, not a store that gives you the games.
Is there an official Portal 2 + Hollow Knight DLC?
No. This is a mashup/mod session. Publish your own variant with Claude Code or Codex.
What does Play do?
It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.
Can I play with friends?
Yes, on multiplayer mashups. Press Play to get an invite link, then keep it private, share it, or go public.
Is Melty safe?
Every upload is checked for dangerous files. If a mashup looks wrong, report it from its page.
