War Rig: A Vessel RPG

In WAR RIG, you and your friends ride atop a mighty machine of metal and fuel. The wheels on which you live carry you from settlement to settlement, searching for supplies and scrap in the wasteland to scrape out a living. But the world is full of many threats. You must rely on each other to survive in the world, but you must also know how to conserve your resources for the good of the group (or, maybe, your own). The world will grind you down, but hope brings you and yours to the next dawn. Hold on to it. Source: The Developer Website.
