Mexican gunman Pedro and his hot girlfriend Juana found themselves in an embarrassing situation. As they drifted through the desert going into the local village to demonstrate where their gun abilities, a zombie apocalypse broke out and today, rather than mad cowboys, they need to protect themselves from hordes of bloodthirsty zombies. They all take is a couple of boxes and their pistols, they would never allow use anybody else. The only chance is these dumb zombies can't jump. Construct a tower out of boxes, snipe that the zombies which are coming and purchase upgrades. Have fun.
