. . "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."@en . "Impulse Launcher"@en . . "Enhanced Flechettes (350) - Flechettes can now hit up to three Bloons.
