Apocobots: Robot Stories of the Future

Two robots, each has a mission in a bleak, post-apocalyptic world. In the story "The Messenger," a robot is tasked with delivering a message across a war-torn city, deep into enemy territory. What is so important? Troop movements? Lines of communication? Attack sequences? No, something far more important than that. 

In "Green," a robot seeks something in the wasteland. There doesn't seem to be anything, or anyone alive. When he's just about lost hope, something appears on the horizon. Is it something that can bring back hope to this worn out world?
