Portalcraft (Portal 2 as a Minecraft player, Stink-O)

Minecraft: Java Edition in Portal 2 · By Stink-O

Plays inside your own copy of Portal 2, on your device, not in a browser tab. Opens github.com in a new tab.

How to play

Have your own copy of Portal 2 installed: the mashup plays inside it.
Download it from its release page on GitHub (it runs on Windows and Linux).
Install it as its page says. What it asks for is just below, in the list's words.
Start the game the way its page says: some mashups come with a launcher of their own.

What it asks for

Portal 2 on Steam and a Minecraft Java Edition Microsoft account; the launcher fetches Minecraft 26.3 and Java. See the README for platform caveats.

In the words of the mashups list, read Nov 5, 2026.
