A ragtag group of gunslingers try to make their way in a post-apocalyptic world. The twist to this world is that it’s just not barren and dangerous, it’s also filled with flesh-eating zombies. The gunslingers will find themselves stranded in a town and forced to make a choice on either to save the citizens of the town or save themselves.

In the distant future, mankind lives on Mars, in cities that resemble those once found on Earth, protected from the alien atmosphere by dome-like force-fields. When a massive sandstorm breaks through the dome and destroys Mars New York, those in Mars Los Angeles must figure out how to stop the storm before it wipes them out next.
