People can always find a way to make a buck. While not "the world's oldest profession" (that'd be something else), paying someone to fight your wars for you certainly goes back a long way as well. And that will progress far into the future as well, as there's a Mercenaries group now available for Polyversal.
This set can be added-on to your Kickstarter pledge, or picked as one of your forces in your current pledge. You get some infantry from Dark Realm Miniatures along with some Grav vehicles from Plasmablast Games.
The campaign has made it over their funding goal. So it's looking to get through stretch goals in the next 9 days.
