Overclock

 is the fourth and final upgrade for the Monkey Engineer on the second path. It gives the Monkey Engineer a Special Ability which enhances a tower's attack speed by 50%, as well as a range boost. This effect lasts for 60 seconds, but as the ability takes 60 seconds to recharge, the ability can be used again immediately. If used on a Monkey Village the towers in it's range will be also be overclocked, but only for a few seconds. Using Overclock on a Banana Farm forces all the bananas out instantly. It costs $11475 on Easy, $13500 on Medium and $14580 on Hard.

Appearance
Once you use this ability, a wrench surrounded by blue fire comes up and you select a tower by clicking on it to give the boosts to. Upon selecting a tower, it will radiate thin blue circles(or green if ios).

Glitches

 * On the Floating Islands track and the Banana Factory track, if you use Overclock on a tower, and the island that the tower is moves to another place, the blue aura won't move with the tower.

Trivia

 * The Overclock Ability takes about 60 seconds to recharge, the same amount of time that the ability lasts for so you can constantly give towers boosts, especially if Hotter Cooldown and High Energy Beacon are both used!
 * It stacks with Monkey Village's M.I.B Call to Arms Ability and with a Boomerang Thrower's Turbo Charge Ability activated.
 * If the Boomerang Thrower's Turbo Charge Ability, The Overclock Ability and M.I.B Call to Arms are all used at once, it will look like there is a continuous line of Boomerangs/Glaives.
 * The official artwork may be a reference to the Eureka Effect Taunt from Team Fortress 2.
 * Overclock can't stack, as seen by multiple test from different computers.
 * the tower boost from btdb ios is a version of this.
 * it is green in ios.
