Dustfall

The world has fallen apart. The apocalypse has started. But not with zombies or monsters, but with robots, AI. Machines of all types have woken, revealing themselves against human race. Their goal is to be the only race on earth. Dustfall, is a city in the outskirts of the capital, Rustwood, where robots have recently arrived and destroyed every thing that moves. But, of course, there are fortresses. They own medical supplies, food, ammo... everything needed to survive enough. Then you come into view. You're a postman/post woman whose orders are to go around every run-down city and deliver things to the fortresses, depending on what they request. Will you be able to survive? Will someone finally fight the robots and stop them? or will this war prevail?
