Increases sentry fire rate appreciably
~ BTD5 & BMC in-game description
Sprockets is the third upgrade for the Monkey Engineer's second upgrade path. It increases the attack speed for sentries and the Monkey Engineer's nail gun. By getting this upgrade, the tier 3 upgrade in the first path cannot be purchased. Sentries that belong to Engineers with Sprockets become SentrySprockets (named in BMC Flash only), if at least the Sentry Gun upgrade is bought. It increases the attack speed for the Monkey Engineer's nail gun by roughly 25% and the sentries by ~50%.
