~ BTD6 description


Spectre is the fourth upgrade of Path 3 for the Monkey Ace in BTD6. Just like in BTD5, the Spectre replaces the usual Neva-Miss Targeting homing darts with rapidly shooting darts and bombs, shooting at a rate of 15 times per second (every 0.06s). Each dart deals 2 damage and has 30 pierce each, while each bomb deals 3 damage and has 60 pierce each. 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[edit | edit source]

Summary[edit | edit source]

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 Top Path Heli in this regard.  

Tips[edit | edit source]

  • 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 instead of 66% for other towers, but every little extra attack speed helps. 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 allow it 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.
  • 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.

Update History[edit | edit source]

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.

4.0

8.0

Trivia[edit | edit source]

  • 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.
