Night 2 sees a significant increase in Springtrap's activity. He will move more frequently and aggressively, making effective use of the audio lure paramount. You'll also start encountering phantom animatronics more often, particularly Phantom Freddy and Phantom Balloon Boy. These phantoms will cause system errors, primarily ventilation failures, which can quickly spiral out of control if not managed. Your focus should be on constantly tracking Springtrap, luring him away from your office, and swiftly rebooting systems when errors occur. Don't let your guard down, as Springtrap can now enter the ventilation system.
