PopCap Games has revealed that it has launched a free Flash-based online version of its tower defense game, Plants vs. Zombies on www.popcap.com . Available exclusively on PopCap’s website, the new Flash-based Plants vs. Zombies provides a way to enjoy endless undead-battling plant-based action and strategy at no cost..

“Plants vs. Zombies is a deceptively deep game that takes awhile to grow on gamers,” said Ben Rotholtz, vice president of Marketing at PopCap. “The new Flash-based version will give prospective buyers a way to sample more of the modes and moments that make up the full game experience.”

In Plants vs. Zombies, players use over 40 zombie-zapping plants like peashooters and cherry bombs to slow down, confuse, weaken and ultimately destroy more than two dozen types of zombies before they can reach your front door. Each zombie has its own special skills, and each plant has its own combat and/or defense mechanisms.
