Blind Faith

Difficulty: Medium-Hard

Blind Faith is an achievement available for iPhone, iPad, PlayStation Vita, Android, and Nook versions of Plants vs. Zombies. It requires the player to complete a very foggy level (levels 4-7, 4-8, 4-9, and their Quick Play variants) without using Blovers or Planterns to make the fog "disappear." It is similar to the Nintendo DS achievement Nebulaphile, however, unlike Nebulaphile, Torchwoods can be used while earning it.



Strategy
It is advisable to have the following:
 * Sun-shroom
 * Puff-shroom
 * Scaredy-shroom
 * Wall-nut
 * Gloom-shroom (with Fume-shroom, of course)
 * Garlic
 * Cactus
 * Garden Rake

To know whether or not a zombie is in the fog, plant a long ranged plant such as the Scaredy-shroom or the Peashooter. The player can use these two plants to sense whether or not there are zombies by attacking them from afar, but plant Puff-shrooms at the beginning of the level because there are not a lot of zombies at the start. Once the player had built his or her sun production, let it produce sun until he or she has enough sun. After that, remove the Puff-shroom and grow long ranged plants.

This achievement requires that the player must not use fog removers. A wise strategy would be to create a defensive line of Garlic backed up by Wall-nuts or Tall-nuts, and Gloom-shrooms on the second and fifth rows.

Trivia

 * The eyes in the icon look like a Wall-nut's eyes.
 * You cannot get this achievement by completing Level 4-1 for the first time.
