Trivia

 * Before September 29, 2013, this upgrade costed $2720 on Easy, $3200 on Medium and $3455 on Hard.
 * In the Flash version of BTD5, this upgrade increases the blast radius size of the central bomb.
 * This upgrade path is better against non-M.O.A.B. Class Bloons while the other path is best against M.O.A.B. Class Bloons.
 * Bloon Impact and The Big One are both upgrades that cause explosions that can pop Black Bloons and Zebra Bloons. Coincidentally they are both the final path one upgrades for their respective towers, and are notorious for the lack of MOAB popping power. Flash Bombs can also pop Black Bloons and Zebra Bloons.
 * This upgrade is useful against large amounts of Ceramic Bloons and other bloon rushes, since it pops a lot of bloons and stuns them.
 * This makes it useful for rounds with Ceramic Bloon rushes like 55, 63, 76, and 78, although it does need support for Camo Bloons.
