Impulse Launcher

"With its built-in mini Bloontonium reactor, the Launcher fires special flechettes that can pop almost any Bloon. Upgrades can create super powerful Radioactive Shockwaves that can pop huge amounts of Bloons at once." The Impulse Launcher is a mechanical tower designed to pop the large amounts of regular Bloons that inevitably gather under MOAB-Class Bloons. It starts as a fairly poor tower for its cost, with its only pluses being its high range and Bloontonium flechettes, but grows into a strong area-of-effect tower with its upgrades. Its specialized paths allow it to either focus on its original role further, or disrupt and bring down MOAB-Class Bloons with ease.

Statistics

 * Range of 140 pixels.
 * Fires two flechettes every three seconds.
 * Cannot spot camouflage.
 * Pops one layer of one Bloon per flechette.
 * Ignores Bloon resistances.
 * Base cost of 800.

Path I - Siege Launcher
Enhanced Flechettes (350) - Flechettes can now hit up to three Bloons. Only the first Bloon hit is counted for shockwave purposes in later upgrades.

Radioactive Shockwave (1200) - If a Launcher fires on the same Bloon twelve times, a Radioactive Shockwave is triggered that removes three layers of any Bloon in a 60 pixel radius.

Siege Launcher (2750) - The Launcher converts to a Siege Launcher. Improves range to 150 pixels, and reduces the flechettes needed for a shockwave to six. Shockwave damage increased to four layers.

Ability: Reactor Supercharge (8000) - Allows the launcher to create a shockwave with every flechette and fire 50 percent faster for a period of fifteen seconds. The ability recharges over one minute.

Path II - Magma Thrower
Improved Cyclers (600) - Fire rate is improved to one flechette per second. Gives a ten percent chance that the Launcher will fire two flechettes in rapid succession.

Unstable Reactor (750) - Fire rate is improved to three flechettes every two seconds. Every fifth flechette will create a small explosion that removes one layer of Bloons in a 20 pixel radius independent of radioactive shockwaves.

Magma Thrower (6000) - The Launcher converts to a Magma Thrower. Fires radioactive flame that has a 5* damage multiplier on MOAB-Class Bloons and fires four times per second. Radioactive shockwaves will trigger after one second of sustained fire if purchased, but will only pop one layer of Bloon. Range reduced to 100 pixels.

Blaze Thrower (5000) - The Thrower now fires five times per second and range increases to 120 pixels. Radioactive shockwaves now start at popping two layers in a 40 pixel radius, and increase in radius for every second fire is held on the target Bloon (so after four seconds of sustained fire, the radioactive shockwave will have a 100 pixel radius). The maximum radius is 140 pixels.
