Gunman Taco Truck is an action-packed drive across the post-apocalypse United States to reach the safe haven of Winnipeg, Canada, where there are no taco trucks and your family’s taco business can thrive. Getting to the safe towns is hectic but your truck is armed with weapons that blast mutants into taco fillings. In the towns you serve up the mutant scraps to struggling survivors who are more picky than they should be. Use money earned and scrap metal found to upgrade your truck and buy gas and supplies for the trip to the next town.

Your goal is Winnipeg, Canada, where there are no taco trucks and it's safe from the annihilation of the United States nuclear accident. You will keep your family business alive and show Winnipeg what REAL tacos are all about.
