Build v159 of Mindustry is now available.

Mindustry is a mix of factory-building simulation and tower defense, where resources move along conveyor belts while bases are defended against waves of enemies.

The main addition is a new asset system that lets sounds, music, images, blocks and items be added to maps or servers - very close to what JSON mods offer, but without any manual downloads. The developers warn this system will likely have serious bugs, so hotfix releases are expected to follow. Anyone wanting more detail on blocks, items and game mechanics can check the official wiki.

This release brings a new system for adding arbitrary content (sounds, music, images, blocks, items, etc.) to maps or servers. In terms of functionality, this is very close to what JSON mods can provide, except without any manual downloads necessary.

Servers can add content by dropping files into the appropriate assets/ subdirectory next to the server JAR. Note that patches have been moved into this directory as well.

This system will likely have serious bugs, so expect hotfix releases after this one.
