Spiked Mines
Spiked Mines is the 4th upgrade of Path 1 for the Spike Factory in Bloons TD Battles 2. When compared to its BTD6 counterpart, it mostly matches BTD6 pre-33.0 stats, although the lifespan of mines without 4-0-1 is reduced to 40s. Each spiked mine has 14 spikes, dealing 2 damage plus an extra +6 to Ceramics and +1 to Fortified, and upon depletion of pierce it creates a powerful explosion. Each explosion creates a blast of 28 radius that deals 10 damage plus +2 and +1 to Ceramics and Fortified, respectively, onto up to 60 bloons, plus a napalm damage-over-time that deals 1 damage every 2 seconds for up to 6 seconds. Both spikes and explosion do not further increase Fortified damage unlike its BTD6 counterpart. Spikes last for 40 seconds, 75 seconds if using the 4-0-1+ crosspaths.
It costs $9,500, and is unlocked with the purchase of Spike Factory.
Strategy[]
Summary[]
This upgrade specializes mostly in grouped popping power, but is too expensive to be used effectively for pure damage, only for stockpiling in conjunction with a stable defense. Mines have high pierce and excels at cleaning up the remains of bloons. Mines deal double damage if they expire instead of being directly detonated, so you could pair this upgrade with middle path upgrades on maps such as Dino Graveyard to deal strong, passive explosion damage to passing bloons. Bottom path upgrades makes the mines last longer and thus be less quick to detonate.
Tips[]
- 4-2-0 and 4-0-2 crosspaths both have their uses. However, 4-0-2 has a stronger stockpile potential while 4-2-0 has faster refreshment, allowing it to stockpile faster and also act better for offense.

Trivia[]
