Platinum Bullets

Platinum Bullets is a passive item and a bullet upgrade.

Effects

 * Increases damage and fire rate with every bullet that hits an enemy.
 * Weapon fire rate doubles every 250 normalized seconds of firing (2500 shots with a ten-shots-per-second weapon), to a maximum of triple firing speed after 375 seconds of shooting.
 * Weapon damage dealt doubles every 500 normalized seconds of firing (5000 shots with a ten-shots-per-second weapon), to a maximum of triple damage after 750 seconds of shooting.
 * Platinum Bullets start partially powered; there's a large immediate bump in fire speed and damage if the item is acquired on a later floor.

Trivia

 * If the player had Gold Junk, killing an enemy would spawn 1-6 extra in addition to the enemy's other loot.
 * The line "Over One Million Served" is a reference to the McDonald's Restaurant's common sign slogan of "Over 99 Billion Served".
 * The item and drop line both reference the phrase/concept of "going platinum", meaning to reach 1 million (or more) in total sales. It was revealed by the Enter the Gungeon twitter account that in July 2017 they reached this merit.
