Frequently Asked Questions
How do I unlock new biomes?
Complete all levels of the current biome to unlock the next one. The Farm biome is free. Snow, Beach, and Space biomes are available for purchase after completing the previous biome.
How do I restore my purchases?
On the map selection screen, tap the "Restore Purchases" button. This will restore any biomes you've previously purchased. Make sure you're signed in with the same Apple ID used for the original purchase.
Why can't I place a tower?
Towers cannot be placed on the enemy path. You also have a maximum limit of 8 towers, 6 ammunition producers (hens), and 2 building material producers (sawmills) per level.
Why won't my tower fire?
Towers require ammunition to fire. Build hen houses to generate more ammunition over time, and collect resource drops from defeated enemies.
What are powers and how do I use them?
Powers are special abilities unique to each biome. Tap the purple Powers button during gameplay to access them. You can use one power per level, so choose wisely!
