Super Mines (BTDB2)

- BTDB2 description

Super Mines is the 5th upgrade on Path 1 of the Spike Factory in Bloons TD Battles 2. It is very similar to its BTD6 counterpart, except with a much lower cost. It also uses the BTD6 pre-29.0 stats.

It costs $130,000.

Summary
Extremely expensive, and often unnecessary unless amassing huge sums of money such that this upgrade can be remotely purchasable. Also doesn't help that it is subpar against Fortified BADs or even just BADs.

Tips

 * There is no point going for 5-0-2. 5-2-0 offers more attack speed, and the bonus lifespan and directedness of spikes is completely useless.
