War Riders is set in a Mad Max like desert wasteland where the last available resource on the earth is Benzene. In War Riders you either mine Benzene or you won't survive. You'll also need to purchase a vehicle first to get started. Benzene is the in-game currency, and you will be able to use Benzene to purchase armor and upgraded guns for your vehicle, etc. All in game currency (Benzene) can be traded for Ether as you progress in the game, and you'll need Ethereum to purchase more vehicles, garages, parts etc.
Vehicle mods and trading between players for War Riders will start in the fall, and the Beta version will be out by the end of the year. However, right now is your best chance to purchase premium vehicles that won't be available much longer.
