Modifiers can be placed on platform tiles instead of towers. They affect the surrounding 8 tiles with various beneficial effects, though often with certain trade-offs as well. They're also more economically flexible than towers, being sellable for greater percentages of their original costs than towers generally are - they can be sold for their full price 5 minutes after placing them. If sold earlier, they will return 75% of the coins.
Modifiers can be unlocked most commonly via Research, where upgrades to the quantity and quality of each can be purchased; and less commonly via specific Trophies.
Modifier price increases for each matching modifier already in play, with compounding cost increases that vary by type (details for each type are provided below).
