Spiked Mines

"Rigged with heavy explosives, the spiked balls are set to go off when they lose all their spikes."

- BTD5 Official Description



Spiked Mines is the final upgrade for path 1 of the Spike Factory in Bloons Tower Defense 5. Each spiked ball can pop up to 16 bloons before exploding. It cost $11900 on Easy, $14000 on Medium, and $15120 on Hard. There is a skull on top of the spiked mine production chute, and a skull on top of the mines it produces. This upgrade rigs the spike balls with heavy explosives. So, the spike balls are set to go off when they lose all their spikes. The explosion sets bloons on fire and pops them every 2 seconds for 6 seconds. The popping power of the explosions are equal to 1-0 Sniper Monkeys (pops 4 layers). Basically, if you have more than one, the mines will create a powerful blockade, most of the time.

Trivia

 * The explosion's side effect is the same as a 0-2 Mortar Tower.
 * This upgrade causes deployment speed of the Spiked Mines to increase rapidly.
 * The Even Faster Production upgrade will enable the tower to produce spiked balls hypersonically and can destroy a whole bunch of incoming Ceramic Bloons at once.
 * Similar to Bloon Impact and The Big One explosions, spiked mine explosions are powerful enough to penetrate Black and Zebra bloons' anti-bomb shells.
 * Spiked mines with Even Faster Production upgrade can kill an MOAB and cripple a BFB shell clean.
 * If Spiked Mines is near a Monkey Village with Jungle Drums upgrade, with Even Faster Production, Spiked Mines will shoot Spiked Balls as fast as a Turbo Charge Boomer with the Ability activated.
 * If the Spiked Mines are not used, they will explode after a while.
 * Due to the doubling of popping power and the fact that with the Even Faster Production upgrade, this tower produces mines at 2x the speed of MOAB-SHREDR Spikes, This tower is as effective against MOAB class bloons as a single MOAB-SHREDR Spikes tower (Not including the explosion.)
 * Spiked Mines is so borderline overkill, that 3 with even faster production can solo rounds 85+ on hard, on the castle track.(*jaw drops to floor*) Just 1 small problem: you need tack awesomiser and big bloon sabotauge premiums. if not, then you would need 12 spike factories (4-2).
 * It looks like the dart monkeys (4,0) spiked balls
