Adapted from opekope2/Space Engineers Plugin Loader Linux.md
As I am new to Space Engineers and the plugin community, I was looking for solutions to run the game with plugins on Linux and found little support. I hope this helps others who come after me.
Due to changes in how the new Pulsar v2 is structured in the release zip file, the current version of StarCpt/SpaceEngineersLauncher (v1.0.10) is unable to handle unpacking and installing Pulsar. In addition, the new StarCpt/Pulsar-Installer is not very practical on Linux. The old loader will not be used for Pulsar going forward, so you will need the following steps to get the game working.
