Inventory

This is a new game feature in BTD6. It allows you to store your smaller towers by putting them into the 'inventory' by pressing a button that says 'store' next to the tower priority selection. It costs $10 to put a tower into the inventory, and $0 to bring it out. You can store a maximum of 20 towers in the inventory.

Towers that cannot be stored:

Temple of the Monkey God

Monkey Village

Banana Farm

Monkey Ace

Monkey Buccaneer with Tier 3/4 upgrades
