Bloons TD Battles: How to Win With the $650 Blade Shooter

To win with the $650 Blade Shooter upgrade in Bloons TD Battles, place a Tack Shooter directly on the inside corner of a sharp curve, crosspath it to 2-3 for maximum attack speed, and channel the resulting cash savings immediately into Banana Farms. Because this setup handles early grouped bloons for under $1,900, it allows you to establish an economic lead before transitioning to Blade Maelstrom or selling into dedicated anti-MOAB defenses.

Tower Costs and Upgrades

The 0-3 Blade Shooter replaces base tacks with circular, high-pierce blades. To prevent fast or clustered bloons from slipping through firing gaps, buy both top-path attack speed upgrades alongside the middle path.

Upgrade Tier	Name	Cost	Function
Base	Tack Shooter	$360	Fires standard directional tacks in 8 directions
Path 2, Tier 1	Extra Range Tacks	$100	Slightly extends projectile reach
Path 2, Tier 2	Super Range Tacks	$225	Further widens firing radius
Path 2, Tier 3	Blade Shooter	$650	Converts standard tacks into high-pierce cutting blades
Path 1, Tier 1	Faster Shooting	$210	Increases blade attack rate
Path 1, Tier 2	Even Faster Shooting	$300	Maximizes blade attack speed

Purchasing a complete 2-3 Tack Shooter costs approximately $1,845. This holds natural bloon waves and low-tier eco sends, giving you an alternative to higher-priced early defenses such as a 3-0 Glaive Ricochet ($2,600+) or a 3-1 Ninja Monkey ($2,700+).

Track Placement Rules

The Blade Shooter emits blades in a 360-degree radius, making track geometry critical to its damage output:

Inside turns: Place the tower on the inner corner of a hairpin bend so the blades strike bloons on the approach, along the curve, and at the exit.
Intersection bends: Position the tower where tracks loop back or overlap near the entrance to pop bloons on multiple segments at the same time.
Track border alignment: Nudge the tower footprint as close to the inner curb as possible to minimize blade travel time against fast pink or black bloons.
Wide curves: If the map lacks sharp bends, place the tower at the apex of the curve and buy the 0-2 range upgrades before the 0-3 transformation.

Economic Farming Strategy

Use the low defensive cost of the Blade Shooter to fund early Banana Farms:

Place your first Banana Farm on Round 1 or Round 2.
Upgrade the farm to 1-0 and then 2-0 while relying on a base or 0-1 Tack Shooter for early red and blue bloons.
Buy the $650 Blade Shooter upgrade as soon as your opponent starts sending spaced yellows or grouped pinks.
Upgrade your farms to 2-0 and 3-0 Banana Plantations during the stable early rounds.

Defending Rounds 10 Through 13

While a single 2-3 Blade Shooter handles basic clustered bloons, mid-game opponent rushes require specific preparations:

Grouped Black or Zebra Bloons (Round 11): A 2-3 Blade Shooter on a prime curve can hold these sends, but activate a Tower Boost if bloons begin reaching the curve exit.
Regrow Rainbow Rushes (Round 13): Do not rely on passive 2-3 blade attacks against dense regrow rushes, as cutting outer layers can multiply regrow bloons and create a regrow farm.
Blade Maelstrom Upgrade: Upgrade the 2-3 Tack Shooter to a 2-4 Blade Maelstrom ($2,700) when an opponent sends an all-out Round 13 rush. Triggering the active ability covers the screen in blades and clears clustered bloon layers instantly.

Covering Camo and Lead Weaknesses

The Blade Shooter cannot damage Lead Bloons and cannot detect Camo Bloons. You must deploy support towers before these rounds arrive:

Lead Bloons (Round 10+): Place a 0-2 or 1-2 Mortar Monkey, a Bomb Tower, or a Wizard upstream from your Tack Shooter to strip lead armor so the blades can pop the inner layers.
Camo Bloons (Round 12+): Use a 0-3 Signal Flare Mortar Monkey or a 3-0 Submerge and Support Monkey Sub to remove camo properties before bloons enter the Tack Shooter's range. On land-only maps, place a 0-2 Radar Scanner Monkey Village over your Blade Shooter.

Late-Game Transition

Past Round 18 and into the MOAB rounds (Round 20+), sharp-type blades deal insufficient single-target damage to blimp shells. Take the following steps to adjust your defense:

Keep one Tack Shooter upgraded to a 2-4 Blade Maelstrom near the back of the track. When MOAB or BFB shells burst, activate Maelstrom to clear the resulting ceramic clusters.
Sell any extra, unneeded Tack Shooters to free up track space and cash.
Reinvest the recovered funds into dedicated anti-blimp options, such as 2-3 MOAB Maulers, Super Monkeys, or First Strike Submarines.
