Nepleslia has mercenaries out the back end, and with mercenaries in mind I recommend the plot Scythe. It's 18+ and is a bit slow at the moment, but to give you the gist of it the plot is about a Police/Mercenary/Political group on a planet taking it away from the corporations that are controlling it and forcing it back into the Democratic Imperium of Nepleslia. Some characters could be considered mercenaries while others are more police than mercenary.
Either way, we basically are mercenaries in Police uniforms.
