Monkey Knowledge Points

Monkey Knowledge, not to be confused with Monkey Knowledge Packs from Bloons Monkey City, is an upgrade system within Bloons TD6. This menu has upgrade trees for primary towers, military towers, magic towers, support towers, heroes, and powers. Each tree features many upgrades for monkeys that can be unlocked with Knowledge Points. After level (add level idk) each level up will reward you with 1 Knowledge Point to use here. Some upgrades cost more than 1 Knowlege Point, and are lower on their tree. Previous upgrades have to be unlocked to unlock upgrades further down the tree that are more powerful.
