Faster Barrel Spin (BTD6)

"Makes gun fire much faster."

- In-game description

Faster Barrel Spin is the Tier 2 upgrade of Path 2 for the Dartling Gunner in Bloons TD 6. It increases the fire rate of the Dartling Gunner by +50%, firing darts every 0.133s instead of 0.2s. Because it inherits properties of Advanced Targeting, a Dartling Gunner with Faster Barrel Spin can pop camo bloons by default.

It costs $805 on Easy, $950 on Medium, $1,025 on Hard, and $1,140 on Impoppable.

Summary
Faster Barrel Spin increases the attack speed of the Dartling Gunner by a considerable amount, making a well-placed Dartling Gunner with this upgrade more reliable than multiple base Dartling Gunners versus single targets. In addition, it is cost-efficient for a Dartling Gunner to use this upgrade as the crosspath with other upgrades, especially the Dartling Gunner's adjacent Tier 3 upgrades Laser Cannon and Buckshot.

Tips

 * This upgrade should be bought in combination with other upgrades.
 * Faster Barrel Spin with Focused Firing can hit single targets at a faster rate with higher accuracy, while adding Laser Shock adds a slight damage-over-time effect to damaged bloons.
 * On the other hand, Faster Barrel Spin with Powerful Darts is effective at popping larger groups of bloons.

Trivia
