Plants vs. Zombies - Nintendo DS

Plants vs. Zombies belongs to the "tower defense" sub-genre of casual games, where the objective is to deploy a series of stationary weapons to protect a structure against hordes of enemies. Plants provide the artillery, and can be bought with sun power, the game's currency. The enemies are zombies invading a suburban lawn. At the start of each level, the player starts to plant the available seeds on the lawn in a strategic manner. Zombies slowly begin to appear from the street at the right side, just a few initially, and must be destroyed before they can reach the house on the other side. Sun power icons falls from the sky randomly, and must be collected with the mouse to increase the funds. The sunflower can be planted to generate extra units of sun power, but doesn't have any attack power against the invading undead. Besides their cost, the seed packs take some time to recharge after being used.

There are several types of offensive plants available. Pea shooters are the basic variety, spitting a projectile forwards every few seconds. Variations appear later in the game, shooting several peas at the same time and freezing the enemies, making them move slower. The carnivorous plant gobbles up a zombie when he gets near its gaping mouth, but takes some time to do so, becoming ineffective while busy digesting the corpse. The cherry bomb explodes after being deployed, carbonizing any of the undead surrounding its landing spot. The potato mine is half-buried with a sensor sticking from the top, and detonates when one of the walking dead steps on it. Plants can be removed with the shovel to make space for new ones.
