[Engine Heart 01] • Mars Needs Sprockets

Humanity is gone; dead, in space, or underground vaults nobody can say for sure. Granted most of what's left are the little servie robots humanity used to depend on for drudge work and they're more concerned with finding power and parts than 'where did the creators go' but that's not much different than how most people acted when they were around. 

This was how life went for one quiet little suburban neighborhood and would have kept going like that until a pod from Mars crash landed in their collective back yard. Finding parts isn't exclusive to hedge trimmers and children's toys it seems. The Martian colonies grow restless and want to start expanding; trouble is to do that they need parts, and for that they need earth.
