Spike Storm (BTDB2)

"Spike Storm Ability: Shoots out a thick layer of spikes over the entire track."

- BTDB2 description

Spike Storm is the 4th upgrade on Path 2 of the Spike Factory in Bloons TD Battles 2. It is similar to its BTD6 counterpart, except without an initial cooldown and its ability is affected by attack speed buffs, much like BTD6 pre-27.0 Spike Storm.

It costs $5000.

Summary
Spike Storm is much more powerful in Battles 2 than BTD6, mainly due to the much shorter track length (and therefore denser spike piles) and the removal of an initial cooldown. It notably has enormous synergy with Call To Arms and Homeland Defense. This allows the Spike Storm to become extremely strong, distributing widespread damage across the whole screen with enough power to obliterate an entire opponent rush at the cost of major lag. Even in regular situations such as weakening a moderate DDT rush is worthy for using Spike Storm.

Spike Storm's storms of spikes dish out huge damage to blimps across the map, making immediate blimp damage its expertise. Spike Storm ability is also works against bloons, but other options for cleaning up regular bloons (e.g. Maelstrom) are far more efficient in that way.

Tips

 * 2-4-0 is generally better than 0-4-2 in almost all situations. There are no such alternating lanes in BTDB2, making 0-4-2 totally redundant. It is not known whether 0-4-2 ability is affected by Smart Spikes in this game.
