Better Off Dead

Difficulty: Medium

For strategies, see I, Zombie or Puzzle Mode.

Better Off Dead is an achievement for PC, iPhone, and iPad. To unlock this Achievement, simply eat all the brains ten times in a row in I, Zombie Endless, reaching a streak of ten.

Strategy
When attempting this achievement, one should first make sure to take out Umbrella Leaves and Magnet-shrooms, as many Zombies rely on metal objects. In rows without Kernel-pults or Fume-shrooms, Ladder Zombies are suggested, as their ladder shield effectively protects them from Snow Peas. Removing the Snow Peas should be your next priority, after the Umbrella Leaves and Magnet-shrooms. If you like to use Digger Zombies, make sure Split Peas and Starfruit are eliminated, especially to protect your Imps. Torchwoods and Threepeaters should also be wiped out as soon as possible. Spikeweed is a lesser threat but tread with caution when using Imps, as they'll only survive one hit after crossing Spikeweed. Use Dancing Zombies against rows with forward fire, as the Backup Dancers will be the ones killed. Do NOT use Dancing Zombies against Spikeweeds.
