Arrow

"Fast zombies! You know what to do!
Units that can slow make quick work out of these guys.
You'd think they'd learn but I guess they've lost their brains long ago!"

―Commander dialogue on Wave 19 (Headache Headquarters)

"Very quick zombies are closing in fast!
Get a unit to slow these guys down or we may have a problem."

―Commander dialogue on Wave 19 (Formerly, Headache Headquarters)

Description

The Arrow was an enemy that appeared in Headache Headquarters, replacing the Bolt. Currently, it only appears when the Brain Rot modifier is activated in Sandbox mode, replacing every modern Bolt variant, or with its Logbook. It has a fast speed and high health, which makes it dangerous.

Appearance

The Arrow consists of three blue arrows that move on the path.

Headache Headquarters Strategy

As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in Headache Headquarters is listed instead.

• High DPS towers, like the Minigunner, Accelerator, Pursuit or Engineer are recommended against this.
  • The Commander and DJ Booth can be useful at boosting their firerate and range respectively.
• As this spawns in hordes, crowd control towers like the Mortar, Rocketeer or Electroshocker can be useful at clearing it out.
• As its quite fast, stalling towers like the Brawler, Frost Blaster, Freezer and Cryomancer can be quite useful.

Trivia

• When the Arrow spawns, it uses the sound "bass.wav" which originates from a CD in 1992 called Datafile Three. This was the sound that was used at the start of a wave around 2019 and 2020.
• The Arrow is the arrow that appears at the entrance of the map and goes to the exit, though it is colored blue.
• The Arrow existed in the game before being added to Headache Headquarters, though it would have 9,000,000,000 health, being the highest amount of health in game. It could have only been spawned by an admin.
  • There also could've been a Kill ENEMY! Quest for the Arrow, despite it not being added yet.
• The Arrow might be a reference to the Arrow Boss from Tower Blitz.
