← Spiked Ball Factory

Spiked Mines is the Spike Factory's path 1 tier 4 upgrade in Bloons Monkey City. It upgrades the spiked balls from the previous upgrade with Spiked Mines, each spiked mine:

• Is thrown every 1 second.
• Has 21 pierce (instead of 20 on the multiplatform version).
• Explodes after all its pierce is used or when it terminates, each explosion:
  • Has 40 pierce.
  • Does 4 damage initially.
  • Applies a burn effect to bloons which does 1 damage every 2 seconds for 6 seconds.

However, on the multiplatform version, it is bugged to no longer deal +2 damage to Ceramic Bloons, and the explosion is also bugged to not soak through layers.

Strategy

Spiked Mines has consistent grouped cleanup in the Flash version, being an effective option at dealing with large amounts of Ceramics. In the multiplatform version, the inability to soak the explosions through multiple layers combined with the lack of Spiked Ball Factory's Ceramic damage and lesser speed boosts of its crosspaths makes it significantly less effective.
