That's right: this mod adds a complete new Vault based on the popular Five Nights at Freddy's series! In this Vault, which is located at the top-center part of the map, you'll find the Arena - a maze-like place to test your skills and see how well you can do at a deadly game of hide and seek. Can you make it from midnight to 6 AM without dying from radiation or crazy robots?
This is the full release of the mod, version 1.87f. Contains all files. Make sure to overwrite all old files if you're updating from a previous version.
