Plants vs. Zombies blooms into its 7th birthday by bringing back a flamethrowing pumpkin

It’s time to celebrate the Seven Years War. No, not that one.

Plants vs. Zombies, a tower defense game where players use viscous flora to stop waves of the walking dead, turns 7 years old on May 5. It spawned a franchise that has expanded to multiple platforms, including PlayStation 4 and Xbox One thanks to the Garden Warfare shooter games. To celebrate, Electronic Arts is introducing birthday-themed costumes in Plants vs. Zombies 2, a free-to-play game for iOS and Android that has achieved over 25 million downloads. The mobile industry is worth $34.8 billion a year. Special events like this can help keep players engaged and push them to buy more content.
