This strategy game from PopCap blends together elements of castle and tower defense.
Like other PopCap games, Plants vs. Zombies is great for its accessibility. The game gradually introduces new gameplay elements at a rate that never feels overly complex -- even when dozens of enemies get involved, and an even greater number of defenses must be employed. Both casual and regular gamers will find themselves enamored by this fun title.
Strategy games and iOS are a match made in heaven. The touch screen makes interacting with units and maps quicker and easier than any mouse pointer could. This has led to a wide variety of fun and intuitive strategy games made for the platform.
