Cluster Grenade
"Throws a Cluster Grenade at the nearest building that not only explodes, but also peppers the area behind the target with explosive shrapnel."


  • Cluster Grenade is a Hero Ability that can be used by Sgt. Brick in attacks.
  • It fires an initial shell that heavily damages its target and then explodes into shrapnel which peppers the area behind the target.
  • It can be used to trigger Mines, Boom Mines, and Shock Mines.
  • Each shot costs 3 more Energy than the previous, with a starting cost of 3 Energy.

Offensive Strategy

  • Since the Cluster Grenade is cheap compared to the Barrage, consider using it as an alternative.
  • The Cluster Grenade fires many shells in a fairly large area in front of your troops, so it can be useful for taking out mines that they are approaching.
