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.


  • !!Error: Invalid EICONS input! When using the Snowman Cannon, neither the primary nor secondary explosions will deal damage to the wielder.


  • While very expensive, the Cluster Rocket I is slightly better than other rockets for large events like the Lunar Events.
  • Stynger Bolts have a very similar function while costing a fraction of the price of Cluster Rockets. This option trades cost for versatility, as Stynger Bolts can only be fired by the Stynger.


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