All survival servers and the two main creative worlds have been uploaded here: https://alttd.com/worlddl. They have been compressed using the 7z format because we’re limited in how much data we can transfer on the service we’re using to host the files. This means you will need to extract the world using 7zip which you can download here: https://www.7-zip.org/download.html.

The download includes all warp coords in an excel sheet (courtesy of PunchyFoil15). And we might add the world maps later as well (in png format).

Steps to be able to play on the downloaded world:

1. Right click the file you want to download and click download
2. While waiting ensure you have 7-zip installed
3. Extract the file into %appdata%/.minecraft/saves
4. Play!
