Throws out secondary bombs instead of frags - causing widespread explosive poppage.
~ Description

Cluster Bombs is an upgrade to the Bomb Tower that made its debut in Bloons TD 5. Its first ever appearance was in the Bloons TD 5 trailer which was released on Nov 29, 2011.

It is worth to note that this upgrade does prevent the Bomb Tower from destroying Black and Zebra Bloons without the aid of a Level 3 Bombing Range (BTD5 only) or a Monkey Intelligence Bureau. However, in BTD5, the Bomb Tower can be upgraded to Bloon Impact to be able to pop Black and Zebra Bloons without any other aid; similarly, in BTD6 this can be done by upgrading to Bomb Blitz, though that is much more expensive.



  • Use this upgrade to pop many bloons at once. Its primarily purpose is to expand its explosion range across many more bloons through the addition of extra explosions.
  • The 2-0-3 Cluster Bombs crosspath is usually better, as its secondary explosions can deal much more damage to bloons that the larger explosions can touch.

Update History (Bloons TD Battles Mobile)Edit


Buff Cluster Bombs price decreased ($800 → $700).



  • When Bloons TD 5 was first released, a Bomb Tower with this upgrade could pop Black Bloons and Zebra Bloons. This has since been fixed.
  • Mass amounts of these are extremely effective against non-M.O.A.B. class bloons, especially when used with the third upgrade of the Bombing Range activated.
  • In the Beta version of Bloons TD 5, Cluster Bombs in conjunction with Missiles would launch missiles that split into more missiles. In the release version, missiles would split into bombs.
  • The primary bomb with this upgrade has a slightly larger explosion radius. The secondary bombs explode with the same-sized radius as a primary bomb without this upgrade. The opposite seems to be true in the mobile versions of BTD5.
  • A 3-0 bomb has a maximum popping power of 360 bloons.
  • It is named Cluster Bomb Shooter in Bloons Monkey City.
    • This stays the same, even when upgraded to 4/x.
  • In Bloons TD 6, the cluster bombs do less pierce than the main bomb - 10 as opposed to 18.
    • This increases to 20 pierce when upgrading to Bigger Bombs.
