This weapon infuses ancient myth into a highly-modified grenade launcher. By utilizing rounds filled with the long-forgotten alchemical solution known as "Greek Fire", the Grenadier is well suited to burn their unholy targets to the ground.

While other types of ammunition have been created, the Holy Fire round is standard issue
