Infinity

The Infinity is a post-Moon Lord gun that drops from the Moon Lord. It is the rare variant of the Shredder. The gun rapidly fires two streams of bullets that swerve up and down to form a helix shape. The gun has two firing modes. Pressing left-click will cause the gun to rapidly fire out energy bolts that explode into smaller bolts that bounce after traveling a short distance. Pressing right-click will cause the gun to rapidly fire out whatever bullets the player had currently equipped. Once fired, the Infinity will not stop firing until 30 seconds have passed or the player logs off of their current world.

Trivia

 * The Infinity is a reference to the gun of the same name from Borderlands 2.
 * The Infinity is the slowest attacking weapon in the game, taking thirty seconds of real time in-between shots without any speed modifiers.
