Like microwavable Tex-Mex, Zombie Farm fuses two populist mainstays into a totally indulgent quick fix. The daily crop management of Farmville meets the zombie invasions of Plants vs. Zombies. Except in this case, you raise both the plants and the zombies, and you are attacking other people for gold and brains. You're really an evil farmer building an undead green empire, and unexpected twists like that are what make the game work. While Zombie Farm apes the visual style and appeal of its two predecessors to the point of being a clone, its shameless mixing-and-matching of them has created a worthwhile, if imperfect, mutant.
