When you acquired an old abandoned nightclub, you never imagined that it was merely a facade for a secret facility, an underground factory. Made to create animatronics far more advanced than anything before them.

On your first night there, the power went out. As you descend into the basement to check the issue, the floor collapsed under your feet and you fell into an underworld of tunnels, steel and concrete.

Once created by an eccentric scientist on his descent into madness (or success?), now lays long abandoned… or so you thought. Something was there with you…

As you barely escape from their grasp, you realize one thing: these aren’t your usual 'click and clack' animatronics. They were state-of-the-art sex machines with only one thing on their mind: Fuck your brains out.

Gameplay Basics:

Fazclaire's Underworld is a free-roam style FNAF fangame. In order to survive the night you will need to explore beyond the office and embark into a thrilling series of quests (given to you by Marie) to restore the facility and ultimately reach the surface.

But be aware! Dangerous (and horny) animatronics will be hunting for you. Fortunately, you can distract them by fulfilling their personal requests.

Every night a new animatronic will activate, so escaping from them becomes harder as your progress. [As for the current version of the game (v1.0.0), only the first night (Frenni’s chapter) is ready.]

Animatronic Mechanics:

Every animatronic has her own set of quests, which will reveal an interactive scene on completion.

While keeping just one animatronic at bay may sound easy, having a whole harem demanding your constant attention can become quite tricky.

Don’t let their requests pile up or expire, or else their satisfaction level will plummet and they will enter rage mode, which, trust me, you don’t want to happen.

On top of that, some of the girls might get angry if you pick one over the other when both ask you the same thing.

And if all of that fails… you can always hide in the control room. No animatronic can't get post its doors… unless you ran out of power.

Scenes and Animations:

Keep in mind that most scenes won't trigger immediately after completing a quest, you will need to wait for the animatronic to reach her intended destination. After that, just get close to her to enter the scene. Time spent watching scenes don't count as in-game time, so take as long as you need.

Items and Energy:

It could not be a real FNAF fangame without some sort of power shenanigans. To keep the lights on and the cameras working, you will need to refuel the generator from time to time. Always keep an eye on the power meter, it tends to run out at the worst times! And yes, the blast door will open if the power runs out.

Some consumable items like batteries and energy drinks can greatly help you survive, while tools will allow you to destroy, open or disassemble, things to unlock new areas or harvest resources from scrap machinery.

Have in mind you can only carry so much, so inventory management is key. Drop what you don't need, it won't despawn. Move things around ahead of time, and get things ready before you need them.
