It was a city at one time, a huge city. Whatever emptied it of its denizens is long forgotten.
The buildings and streets suffer from what looks like two decades of decay, neglect and minor warfare.
The alleys and sewers and subway systems are infested with twisted creatures, and are studded with mysterious machines.
The rooftops bear the only signs of recent habitation, but what would cause people to flee to the rooftops, to bridge them together with rope and wood and steel...?
Are there even any people here at all?
Were there ever?
This City is the Pit, and you will wake here wondering where it is you are, why you are there, and how you even got there.
You hurt, you ache. Your memory seems faulty.
There is a silvery device embedded in your body.
After fifteen minutes, it will be all you can do to survive. All you can do to survive is accept the urge the device, the blasted tick-like thing on your arm, is pumping into your very blood. Find a partner. Someone. Anyone. Another person will help you to survive.
The device may even remind you, somehow, that you have been altered. Enhanced....
But...
Even if you do survive, the Pit seems to have no connection to anything, a cliff-rung fortress of an island in the middle of an unforgiving ocean. Any and all boats have been destroyed, and the only airstrip is a den for the twisted creatures that rule the streets.
This and more can be learned by observation alone, however...
What you don't know is that you are being watched. Those giant machines? Monitoring the entire city as if it were a contained ecosystem. And oh, it is. Behind the mirrored glass, eyes are watching, calculating, gathering data.
You are an experiment. You are a statistic. But all you'll care about is trying to live another day.
After all, the end will most certainly justify the means.
