Star Three
The third star in this Five Nights at Freddy’s Installment cannot be unlocked until you’ve obtained the second star. That’s because beating that mini-game will grant you a Keycard item that is used to trigger the location for the game’s final ending, which is known as the “Fake Ending.” It’s called the Fake Ending because if you brighten your screen during the credits, it actually says those exact words at the bottom of the screen in the left corner.
Fake or not, this is the hardest challenge to complete. First, you must make it to the fifth night and do everything as normal. Baby will have you remove her endoskeleton to he scooping room, which she will then guide you to, keeping you away from the deadly clutches of Ballora. Instead of listening to her directions, however, you’re going to want to turn all the way to the right and hold down W + D. This will allow you to enter the Sister Location’s secret room. Input the code 1983 in the keypad next to the Celebrate poster. This is where things get tricky.
Ennard is your final challenge and is a tough one to survive. You’ll have access to panels and monitors, but power is limited. Keep an eye on the monitors and close the panels as needed. You must survive until 6 A.M. so stay vigilant. Once you’ve made it, you’ll be back at home watching a movie, only to have Ennard’s endoskeleton show up in your house right before the screen cuts to black. You’ll get your ending and your final Five Nights at Freddy’s: Sister Location star.
