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 nothing that this upgrade does prevent the Bomb Tower from destroying Black and Zebra Bloons without the aid of a Level 3 Bombing Range 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.

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

    • Ah, thanks! This makes them ideal for bloon rushes then, or do you recommend mortar, or something else altogether?  How are mortar at bloon rushes?
    • Personally, I find x/2 Mortars and Cluster Bombs (not Missile Launcher) both ideal for bloon rushes. Cluster Bombs can pop more bloons, but ...
