In 2011 Joosa was approached by arand (Martin Erik Werner) with questions about licensing. It turned out he was making yet another clone based on the OpenLiero source code. The goal was to remove all proprietary content from the game so that it could be included in Linux packages. His version, aptly named lierolibre was released in 2012 and was adopted in 2013 as one of the promoted game versions on Liero.be, so as to give the avid Liero enthusiast complete freedom of choice.
