Smart Spikes
Spike Factory gains special targeting priority and a small speed boost each round.
Tower Path Tier Cost
Spike Factory 3 2 $500

Smart Spikes is the Spike Factory's path 3 tier 2 upgrade in Bloons TD Battles 2. It gains a tower buff at the start of each round that quadruples its attack speed for 2.5 seconds. If crosspathed with Spike Storm and Carpet of Spikes, their abilities will only dispense spikes on paths that currently have Bloons on them. The Spike Factory also gains three new targeting options:

  • Close — Dispenses spikes on the nearest section of track within range.
  • Far — Dispenses spikes on the furthest section of track within range.
  • Smart — Targets whichever track has the Bloons that are closest to reaching the exit (or has Bloons at all), and dispenses spikes on the point closest to the end of that track. If it cannot reach any paths that have Bloons on them, it will dispense spikes on the points closest to the ends of each track within its range, keeping their coverage roughly even.

A decent upgrade for focusing spikes and the start-of-round speed boost, which further pushes the value on short rounds and when stockpiling for longer.
