Harp: T4

Harp is a Tier 4 Tank that upgrades from Launcher at level 45.

Design
The Harp resembles Shotgun, but with a large purple spike layered above the barrel. This spike has a similarly purple base that tapers slightly.

Technical
The Harp has a special bullet called the Arrowhead. Arrowheads deal small damage but knock back tanks. After spawning, Arrowheads travel slowly for a moment, then turn a random direction.

The Harp fires one missile (with a similar layout to the drone) with slow reload. The missile propels itself by firing 5 Arrowheads from its back. It does this 3 times before despawning.

When firing a missile, it also spawns 5 Arrowheads from its back.

Note that the Arrowheads are shaped somewhat like Long Boys, turn at odd angles a bit after being fired, and are always coloured purple regardless of team color.

History
At some point Harp was redesigned, moved to Tier 4 and made to upgrade from Launcher rather than Surgeon.

Trivia

 * Harp's redesign was made by Abyss.
 * The harp is a type of musical instrument. It may have been named after it because the spread of Arrowheads the missile produces vaguely resemble a harp's strings.
 * According to lore, Harp was a failed attempt to recreate Oxyrrhexis.
