Quad Darts (BTD6)

"Shoots 4 darts per volley instead of 2."

- BTD6

Quad Darts is the first upgrade on the first path for the Heli Pilot. It allows the Heli Pilot to shoot 4 darts per volley instead of 2 darts per volley. It is not confirmed whether these four darts count as one single spray or just a duplicated multi-target twin dart attack.

It costs $680 on Easy, $800 on Medium, $865 on Hard, and $960 on Impoppable.

Summary
Generally, Quad Darts is used as an early-game upgrade when using the Base Heli Pilot. Similarly to the lower tier, the Base Heli Pilot finds most use on long tracks and maps where the infinite range is appreciated.

Tips

 * For the middle path Heli, the Quad Darts path offers more early-game damage and the ability to buy the next upgrade, Pursuit. Otherwise, try to go for Faster Darts and Faster Firing as they will boost the effectiveness of Downdraft and the Marine from Special Poperations.
 * For MOAB Shove, it may be better to not buy Quad Darts so that it can stall blimps for longer, but for Comanche Defense and Comanche Commander this crosspath will be the best as they are DPS-oriented and can obtain camo detection from external means.

Trivia

 * When the entire list of BTD6 tower upgrades are listed alphabetically, the Pursuit upgrade comes right before Quad Darts.
 * Quad Darts is the only returning Heli Pilot upgrade below Tier 3 to be more expensive on initial release.
