Operation: Dart Storm is an upgrade for the Monkey Ace, first released in the BTD4 Generation. It increases the quantities of darts to 16 and greatly improves the effectiveness of dart volleys. The Operation: Dart Storm upgrade follows from a different lineage of upgrades; BTD4 Generation sets it as the powerful Ace upgrade along its single-linear upgrade path, BTD5 Generation games follow it from the bombing upgrade path (such as Pineapple Present and Ground Zero), while BTD6 and BTDB2 follow it along an entirely new upgrade path dedicated for high rates and quantities of darts and anti-MOAB destruction.
