Rapidly fires darts and bombs, dominating most Bloon types easily.
~ BTD6 description

Spectre is the fourth upgrade of Path 3 for the Monkey Ace in Bloons TD 6. Just like in BTD5, the Spectre replaces the usual Neva-Miss Targeting homing darts with rapidly shooting alternating darts and bombs, shooting at a rate of 15 times per second (every 0.06s). Each dart deals 2 damage and has 15 pierce each, while each bomb deals 3 damage and has 30 pierce each (45 with 0-1-4), and both attacks deal +2 Ceramic damage. However, the Spectre can no longer damage DDTs without MIB or similar upgrades, even if it has camo detection. Also, the Spectre upgrade is now split from Rapid Fire upgrade, which may potentially force either external camo detection for an attack speed bonus or internal camo detection in exchange for no additional attack speed bonus.

It costs $20,400 on Easy, $24,000 on Medium, $25,920 on Hard, and $28,800 on Impoppable.

Strategies[]

Summary[]

Due to Spectre's high pierce and damage, it is an excellent mid-game upgrade. Its largest benefit compared to other midgame towers is that it has global range, meaning it has additional viability on multipath maps or maps with a lot of length for Spectre to utilise. Due to its high pierce, it can very quickly dispatch heavy bloon rounds such as Rounds 63, 76 and 78.

Do note that however, it can sometimes have subpar damage against Fortified bloons, and becomes weakened once superceramics appear starting Round 81. It is also possible to use Spectre strategy as its own main DPS even in late-game with a lot of support, although it is notable that Spectre is frequently outclassed by towers such as Sky Shredder paired with Stronger Stimulant and Apache Prime in this regard.

Spectre can completely eliminate everything that is not a blimp in less than a second, so use that to your advantage. Although Spectre is very powerful against pre-round 80 Ceramics, it may sometimes miss due to the long travel time of its projectiles, but adding slowdown support such as Bloon Sabotage or Glue Hose or simply micromanaging the Spectre to keep it closer to its targets will help make it miss less often.

Tips[]

  • On Rounds 81+, where subsequent rounds change Ceramics into Super Ceramics that have a set amount of extra health plus extra speed per round, Spectres tend to fall back on power against fast Super Ceramics. Often, the Spectre would fail to target properly on specific positions. However, this can be remedied by placing the Spectre's flight path to one that is more closely placed near the targeted bloons.
  • It is usually better off getting 1-0-4 Spectre as opposed to 0-2-4 Spectre. Rapid Fire adds 33% extra attack speed, which sounds small but it makes a big difference to the Spectre's already high DPS. Lots More Darts crosspath does not add extra darts for the Spectre, but instead adds 25% more pierce to each dart, which generally isn't worth purchasing, unless the player has a glut of money or was using Neva-Miss Targeting.
  • Usually, Spectre micro tries to keep the Spectre shooting down a straight line or hitting multiple bloons to make full use of its dart pierce.
  • Spectre paired with Overclock is a good idea to utilize, because this allows the Spectre to avoid missing its shots so often, as the increased attack speed allows it to adjust to new changes in bloon positions at a much faster rate. Overclock's buff also has full uptime on all Tier 4 upgrades, meaning that the 66% attack speed buff is constant on Spectre.
  • Spectre appreciates both direct support, in the form of damage buffs from Pat Fusty's Rallying Roar and Permanent Brew, but also bloon control such as in the form of MOAB Glue and other Glue Gunners, Bloon Sabotage or Downdraft. Damage buffs help Spectre to have far more acceptable stats while bloon controllers help to deal with weaknesses such as DDTs and superceramics.
  • Spectre always targets on First. During the late-game, focus on destroying any bloons far or otherwise unfavorable for the Spectre, so it will not waste its shots on missing targets.

Version History[]

Before Version 4.0, Spectre was much more powerful than the Apache Dartship for less price. Now, with a very slight nerf to Spectre (but with no change to the Flying Fortress by extension) along with an Apache Dartship price drop has made the Spectre a little more on even grounds.

In Version 8.0, Spectre was nerfed in price but with a damage buff to compensate, mainly to counteract the easy Deflation wins.

Version 23.0 introduced a small buff to Spectre darts, while Version 28.0's rework by increasing Ceramic damage over a reduced bomb pierce is an overall buff, as Spectre bombs have huge pierce anyway that giving both dart and bomb attacks with bonus Ceramic damage still makes a big impact on the most dangerous grouped mid-game rounds anyway.

4.0
  • Nerf Spectre attacks 16.67% slower than normal.
8.0
  • Buff Spectre darts deal more damage (1 → 2)
  • Buff Spectre bombs deal more damage (2 → 3)
  • Nerf Spectre costs more ($18,000 → $24,000)
23.0
[...] In addition to this we are experimenting with adding a small amount of homing to the spectre upgrade as rapid fire missing is not the intended design.
~ Ninja Kiwi
  • Buff Spectre darts now have a slight homing effect.
  • Buff Spectre dart projectile size increased (2 → 3)
28.0
Monkey Ace has had an overall rework to a lot of different upgrades in order to highlight the x1x Exploding Pineapples upgrade as a buff to all explosives, in addition to this Spectre has been reworked to have less base pierce but a higher damage bonus to Ceramic Bloons in order to make the new option of a pierce crosspath more viable while also allowing it to carry on better into the endgame against Super Ceramics.
~ Ninja Kiwi, referring to both Exploding Pineapple rework and Spectre rework
  • Buff Spectre dart damage deals +2 damage to Ceramics, for 4 damage versus Ceramics instead of 2.
  • Nerf Spectre dart pierce reduced from 30 -> 15
  • Buff Spectre bomb damage deals +2 damage to Ceramics, for 5 damage versus Ceramics instead of 3.
  • Nerf Spectre bomb pierce without Exploding Pineapples reduced from 60 -> 30
  • Nerf 0-1-4 Spectre bomb pierce reduced from 60 -> 45
  • Buff 0-1-4 Spectre bomb radius increased from 20 -> 23

Trivia[]

  • The nerfed attack speed Spectre with Rapid Fire shoots at approximately the speed of the Spectre in BTD5.
  • Use of a 0-2-4 Spectre formerly was a simple go-to strategy for almost all Deflation Mode maps, but this was no longer possible in Version 8.0, where the Spectre was pricehiked but increased overall damage to compensate.
  • The BTD5 Spectre upgrade used a "mysterious" description ("Flying fortress of bloon doom"), but in BTD6, the description for the Spectre is fully described in terms of how it attacks ("Rapidly fires darts and bombs, dominating most Bloon types easily").
  • The darts from the Spectre are 2D models, while the bombs from the Spectre are 3D models.
  • It is believed the model for the Spectre has a small resemblance to the AC-130. This is further suggested by the name as older AC-130s were known as Spectre Gunships.
  • There are three window panes on the BTD6 Spectre, while the BTD5 Spectre in both the Flash and Mobile versions had only one longer pane.
  • A "spectre" is a type of ghost or a phantom. Alternatively, it means a "mental image of something unpleasant or menacing" (Dictionary.com definition) or "the idea of something unpleasant that might happen in the future" (Cambridge Dictionary definition). Regardless of how the word "spectre" may be interpreted, the Spectre's dark color scheme and high DPS closely matches the level of ferocity that its name may suggest.
