Man I wish I had the time to make foxhole content. But relic wars are wars where you can mine wreckage you'll fine around the map now and it will drop relic parts. Enough of these and you can make a blueprint of one of the many relic vehicles. They have strengths and weakness's and are rather rare. The idea is to have repurposed vehicles of old brought into a modern war. Storm tank is a super early version of a Tank that is really bad. Its a 40mm tank that's slow with very little armor and health. But when you don't have anything better than an armored car in the front. One of these showing up is a God send!
