Frequently asked

Does Nightmare Mode [BTW ADDON] work on Minecraft 1.6.4?

Yes. 1.6.4 is the newest Minecraft version Nightmare Mode [BTW ADDON] declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Do I need to install Nightmare Mode [BTW ADDON] on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

What licence is Nightmare Mode [BTW ADDON] under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Nightmare Mode [BTW ADDON]?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Nightmare Mode [BTW ADDON] safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
