How to Unlock the Legendary Blockbuster Grenade

Blockbuster is a high damage Grenade that splits into MIRV Grenades on impact, while also causing ALL of them to bounce. It's a simply but splashy effect.

There's a fair variety of different modifiers you can roll, adding some incentive to farm extras if you want to experiment with a wider range.

Unlock Location:

• Unlock the Windspear sub-region of the Terminus Range.
• Proceed to the Umbral Foundry, the Fortress where this region's Main Story boss resides.

Farm Method:

• Defeat Vile Lictor through the campaign.
• Use the Encore Machine to farm until Blockbuster drops.
