The map has got much bigger, there are more different items and much bigger and less linear story.
The second part preserves the spirit and the basic mechanics of the first game, but it has a completely new set of graphics and a whole lot of new features, such as morale, slavery, electricity, different foodstuffs, weapon attachments, tools, workshop etc. Then you can spend the money you earn on purchasing transport, hiring people or improving your battle gear. Buy stuff where it's cheap and sell it where it's expensive. There are different ways to achieve this, but the most straightforward one consists in transporting goods between settlements. Your goal is to survive and to try and gain enough power to complete your mission. You find yourself in a post-apocalyptic desert. The game is a fusion between an RPG with turn based battles and an economics simulator.
