Like the other nights (excluding night one), simply try to keep Springtrap in either camera 9 or camera 10 by triggering the audio, and depending on which one he's in, seal the vents in cameras 11 and 14 respectively. Now all you have to do is constantly reboot all systems to make sure you don't trap yourself in a situation where Springtrap is near and one of the systems isn't working, while also keeping Springtrap in either cam 9 or cam 10, and try not to trigger any of the phantoms (e.g the puppet in cam 8, Chica in cam 7, or Balloon Boy who can randomly appear in any of the cameras.) and you should complete the night.
