Artificial intelligence and war machines and the end of the world as we know it:
In an alternate timeline of our Earth, humanity wiped itself out and left behind sentient vehicles that continued fighting their war until there was little left to fight over.

Although their lives are a perpetual fight for survival in a hostile world, between all the battles and conflict we can find stories of friendship, hope, and kindness.
