Mod of Redemption/Nanobot Launcher

The Nanobot Launcher is a Hardmode magic gun. It fires 10+ nanobots that latch on enemies and deal damage several times, similarly to the Wasp Gun. They can bounce off blocks infinite times, until their lifetime runs out. It is dropped by King Slayer III.

Trivia

 * The part of the tooltip: 'Nanomachines, son' is a reference to a line spoken by Senator Armstrong in Metal Gear Rising: Revengeance.
