The video game Five Nights at Freddy's 4 was released to the surprise of fans a few weeks ago after developer Scott Cawthon had teased a Halloween 2015 debut. Players have since exchanged game tips, spoilers, and discussed strategy and theories. Through it all, no one has yet to uncover all of the game's secrets, Cawthon revealed in a Stream community post.

"You know, when I released the first game over a year ago, I was amazed at how quickly everyone found every bit of lore and story," he wrote. "Then the same happened with part 2, fans and YouTubers dug in and found everything. Game Theory did an incredible video on part 2; getting almost everything right. Then part 3 came out, and once again the story was uncovered by the community. It seemed that there was nothing I could hide!"

According to the Texas-based video game designer, no one has succeeded in discovering the story of the fourth game.

"But then I released part 4, and somehow.... no one, not a single person, found the pieces. The story remains completely hidden," he said.

Cawthon believes that gamers may have assumed that he filled the game with random Easter eggs in the final installment.

"I didn't. What's in the box? It's the pieces put together," he wrote.

While he is surprised the pieces remain elusive, he said that makes the final chapter of the game more special and "a fitting conclusion in some ways, and because of that, I've decided that maybe some things are best left forgotten, forever."

Cawthon also wrote that FNAF4 will receive a game update in October that includes a cheat menu, new challenges and "a twist on a familiar minigame."

Lastly, Cawthon revealed that he is creating a new game, but it won't be a Five Night's at Freddy's installment.
