Bigger shells deliver a bigger blast radius.
~ In-game description

Bigger Blast is the first upgrade of Path 1 for the Mortar Monkey in BTD6. It increases blast radius of the Mortar Monkey's explosions, from 20 to 30, and increases pierce from 40 to 45.

It costs $425 on Easy, $500 on Medium, $540 on Hard, and $600 on Impoppable.



Having a bigger blast radius helps the Mortar Monkey's explosions hit greater numbers of bloons per shot. It is especially useful when located onto small loops like the loops on In the Loop and large loops like the craters of Moon Landing and the large lake of toxic waste on Spillway. As a bonus, the Mortar Monkey gains more pierce, perfect when there's a large crowd of bloons.


  • It is usually better to get Path 2 or Path 3 for the early-game, but Path 1 can be better if there is a good bend or loop around. But for later on in the game, this upgrade is generally the better upgrade for Heavy Shells and Artillery Battery for the better hit consistency, even surpassing that for Increased Accuracy.

Version History[]

So far, the only changes applied here are based on crosspathing changes. However, not adding Path 2 crosspath is buffed overall, with an almost negligible nerf to 1-2-0.

  • Buff Bigger Blast blast radius increased slightly
  • Nerf Explosion random deviation radius increased (18 → 30).
  • Buff Attack speed without Path 2 upgrades increased (2.2s → 2.0s).
  • Buff Attack speed with Faster Reload increased (1.54s → 1.5s).
  • Nerf Attack speed with Rapid Reload decreased (1.07s → 1.08s).
  • Buff Reverted random deviation radius change.
