Ralph - The Cowboy
"You led an easy life for too long. Let me summarize the situation: kill or get killed."
After a successful investment, Ralph earned enough money to buy a quiet ranch and retire. When he heard zombies had come from the city to invade the country, he fortified his house and armed his family to face anything. He was about to let the whole damn world burn when his conscience tickled his mind. He had to go back to the city, find his former friends, and save their butts. The situation is even worse than he expected, but so far, wilderness lessons apply very well to urban survival.
Ralph comes with a free Zombivor model as the Kickstarter reached the Stretch Goal of $1100K.
Ralph resembles the character of Tallahassee, played by Woody Harrelson, from the movie Zombieland.
