Neverllion is a special decoration you get once you reach 2 billion coins (which is 2,000 million coins). After you get that trophy, the game will automatically deduct one billion coins. To unlock the Neverllion achievement, you need to collect several Golden Billion trophies. That’s no easy task, but once you complete it, your name will stay in zombie history forever!
