The Tack Zone (BTDB2)

The Tack Zone is the 5th tier upgrade on Path 3 for the Tack Shooter in Bloons TD Battles 2. It is identical to its BTD6 counterpart except that it has the pre-25.0 BTD6 Tack Zone costs but the post-25.0 BTD6 Tack Zone stats, i.e. a higher cost, sharp damage type, and short base range and pierce with more damage per tack.

The upgrade costs $24,000 and has ??? range, firing ??? tacks, each with ??? pierce, in a radially symmetric fashion every ??? seconds. Path 1 crosspathing will impart increased rate of fire, while Path 2 crosspathing will give the Tack Zone enhanced range and pierce. The tower can not pop camo without external support.

The Tack Zone excels in middle and late game due to its relatively low cost for a tier-5 tower, very high rate of fire, high projectile count and long projectile range. Placing the Tack Zone close to bends in the track will maximize the number of tacks used.

Summary
The Tack Zone is both reasonably inexpensive for a Tier 5 upgrade, works extremely well with Alch buffs, and greatly excels at shredding MOAB-class bloons. It does still suffer from being poor at popping DDTs underneath, but it is formidable against any other blimp type when given the right supports.

Tips

 * 2-0-5 almost always offers the better results. 0-2-5 offers much more pierce and range, but there's always other options for high pierce anyway.
 * Given the versatility of this upgrade, a player will typically have The Tack Zone as their first Tier 5 upgrade in BTDB2.
