In trying times, we must turn to our green defenders, producers of oxygen and pretty smelling flowers. This casual take on the tower defense game features plants vs. zombies, which is fitting considering the game is called Plants vs. Zombies. Other examples in the genre include the less esoteric Defense Grid and the equally outlandish Immortal Defense. Astute regular readers will also notice the similarities between this game and another eternal struggle that has rarely been highlighted: Stalin vs. Martians. Irregular users probably need some Metamucil."
