Really Big Bombs (BTDB2)

Really Big Bombs is the 3rd upgrade of Path 1 the Bomb Shooter in Bloons TD Battles 2. It almost identical to its BTD6 counterpart.

It costs $1200.

Summary
Really Big Bombs is actually better than Cluster Bombs at destroying big rushes of bloons, thanks to its high damage, explosion radius, reasonably high pierce, and opportunity to also have the attack speed crosspath without compromising blast radius. This is especially deadly against large Purple rushes.

Tips

 * 3-2-0 is unanimously better than 3-0-2, as 3-2-0 has greater explosion rate, and 3-0-2 does not offer black-popping for explosives like in BTD6.
 * It is worth adding Striker for the extra attack speed and black-popping chance. It might not seem much, but Striker makes a reasonable difference to helping Really Big Bombs rip through tough bloons.
