As you may know, Voxelands is an open-source sandbox construction game based on Minetest, which is an open-source Minecraft engine. Like other sandbox construction games, the users can build structures and artworks, usable on either multiplayer servers and singleplayer worlds.

The latest version available is Voxelands 15.07.00, which has been recently released.
 Installation instructions:
There is no Voxelands PPA available, but we can download the deb package from the project’s website and install it via command-line. I prefer gdebi over dpkg, due to the fact that it also handles dependencies.
Unfortunately, there is not deb package for 32 bit systems:
How to install Voxelands on Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, SparkyLinux and Robolinux systems:
