Super Mines

Super Mines is the final upgrade of Path 1 for the Spike Factory in BTD6. It makes the Spike Factory shoot much stronger mines that create much larger explosions that deal enormous damage. They produce mines slower than Spiked Mines, however, so it's better off purchasing the Faster Production and Even Faster Production upgrades. It costs $TBA on Easy, $175,000 on Medium, $TBA on Hard, $TBA on Impoppable.

Tips

 * It is better off purchasing the Perma-Spike upgrade for another Spike Factory that is placed at the end before purchasing this tower, since Perma-Spike is much more reliable long-term.
 * It is not recommended using this upgrade as the primary attacking tower, as it is very unreliable against mass grouped normal bloons compared to multiple Spiked Mine Factories for similar price.
 * This upgrade is still very helpful against damaging MOAB-class bloons immensely, especially when the mines explode when timed out. When the mines are timed out, they explode and can damage MOAB-class bloons heavily if explosion reaches MOAB-class bloons.

Trivia

 * If ignoring Super Monkey's 5th-tier upgrades, Super Mines is the most expensive Tier-5 upgrade out of any tower.
 * Despite its enormous explosions, its explosions are limited to popping up to 100 (?) bloons.
