|“||Heavy shells do extra damage to Ceramic, Lead, and all Fortified Bloons. Can also pop Black Bloons.||”|
|~ BTD6 description|
Heavy Shells is the third upgrade of Path 2 for the Mortar Monkey in BTD6. It allows the mortar to pop black bloons as well as deal +1 damage to all fortified and lead bloons (including MOAB-class bloons), +3 damage to ceramic Bloons, and +1 damage to MOAB-class. It costs $765 on Easy, $900 on Medium, $970 on Hard, and $1,080 on Impoppable.
- Since Burny Stuff no longer can apply napalm onto Black Bloons without MIB support, Heavy Shells is a must-need if wanting to pop Black Bloons with a Mortar Monkey.
Heavy Shells with Burny Stuff will now (correctly) add Burny Stuff to Black Bloons.
Heavy Shells now deals +1 damage to MOAB-class.
- There is used to be a bug where a 0/3/2 Mortar Monkey cannot apply napalm to Black Bloons despite the Heavy Shells upgrade allowing to pop Black Bloons. This was fixed on Version 7.0; Black Bloons popped by a 0/3/2 Mortar Monkey will now turn into Pink Bloons with the Burny Stuff effect instead of without the Burny Stuff effect.
- Heavy Shells changes the Mortar Monkey's activation process into pressing a button on a special handheld remote instead of a ground-level lever.
