Zapinator

The Zapinator was a weapon that was accidentally left in the game when released, but taken out in a subsequent update. It resembled an NES-era light gun. This was a weapon that Terraria's creators used during testing without worrying about enemies.

Trivia

 * In terms of damage per hit, most hardmode weapons do more damage.
 * The Zapinator's name and sprite resemble the Nintendo Zapper; A light gun peripheral accessory released with the NES.
 * The Zapinator's projectile ID was 20 (the projectile fired by the Space Gun)
 * With the extreme use time of the Zapinator being 9 (even though the highest use time for a weapon is 7) this makes the Zapinator useless because as soon as you try to use it on your computer, console, or mobile device it will automatically crash or if anything set your frame rate down to .00002 automatically.
