Five Nights at Freddy’s is in fact an indie game which was released back in August 2014. The game caught some traction and popularity and because of this (and the fact it’s a fun game) Kingbudderjr decided to create a map of it Minecraft PE.
In the map you play as a security guard who have to spend the night at Freddy Fazbear’s Pizza. In the pizza place there are malfunctional animals which you have to defend yourself against.
Currently the map is 100% finished and the only thing left to do is the texture pack which is about half done at its current state. In the future the creator also intends to create a mod for the map.
