Shooting the Cluster Rocket I with a Rocket Launcher.

The Cluster Rocket I is a type of rocket ammunition. Unlike the Cluster Rocket II, it does not destroy tiles. Unique from other rockets, cluster rockets shoot out shrapnel that create several secondary explosions.

Cluster Rocket Is can be purchased from the Cyborg for 750 each after completing the Martian Madness event.


  • The Cluster Rocket is very expensive, but if you have a ton of money at the end of the game, it's slightly better than other rockets for large events like the Celestial Pillars.
  • When using the Snowman Cannon, the secondary explosions from the shrapnel do not deal any damage.


  • Desktop 1.4.1: The shrapnel explosions now correctly deal damage when used with the Snowman Cannon.
