PopCap's Plants vs. Zombies continues to spread its roots throughout the games industry (or, from the other perspective, it continues its slow, mindless march across the industry). Today, PopCap's outrageously popular casual strategy game has launched on the Windows Phone 7 platform for $4.99/€4.99. It's part of Microsoft's "Must Have Games" promotion, preceded by Sonic 4 and followed next week by Angry Birds.
The WinPhone version includes Xbox Live integration, including leaderboards and achievements. It also includes the first mobile versions of the "Vasebreaker" and "I, Zombie" puzzle modes.
