Annihilation ability: Destroys most Bloons completely and utterly within blast radius.
~ Official BTD6 description

Tech Terror is the fourth Path 2 upgrade for the Super Monkey in Bloons TD 6. It corresponds to the Technological Terror upgrade in BTD5. Along with +25% increased attack speed, +2 pierce, and shoots green plasma balls instead of darts, it gains an ability to deal 1000 damage to all bloons within range of the annihilation range, including Camos.

It costs $18,700 on Easy, $22,000 on Medium, $23,760 on Hard, and $26,400 on Impoppable.


  • 2-4-0 Tech Terror is generally better for the +2 pierce and double attack speed, though 0-4-2 is good for utilizing the knockback power of the Knockback upgrade and camo detection from Ultravision.
  • Note that upgrading to Tech Terror prevents the Super Monkey from popping Purples without support, unless further upgraded to The Anti-Bloon. Be sure to provide backup defense against Purples, especially Camo Purples.

Version HistoryEdit
