Trivia[ | ]

• Most Bullet Upgrade sprites are designed after either pistol cartridges or shotgun shells. The exceptions to this being Silver Bullets and Chaos Bullets, which are instead designed after rifle cartridges.
• Some Bullet Upgrade items correspond very closely to existing guns, including:
  • Devolver Rounds and the Devolver
  • Vorpal Bullets and the Vorpal Gun
  • Helix Bullets and the Helix
• Having too many bullet upgrades can crash the game.
  • Chaos Bullets may cause the game to crash more often than usual.
  • Having Orbital Bullets and the Yari Launcher with the Shadow Warrior synergy active, causing the demon head to fire will cause severe amounts of lag.
