Before the lab, there was nothing. Then the Underground busted you out. 
Their plan was to take a small amount of your blood, enough to prove the 
Factors are tampering with human genes. Unfortunately, their spies didn't 
expect you to be alive. Now you must fight your way past the crack troops 
and inhuman experiments of the Deciding Factor. And they're willing to 
spill a much larger quantity of blood. In fact, they'd prefer to.

Getting out alive is just the beginning. Your new allies follow the Oracle, 
the leader of the human church. The problem is, he's been in a trance for 
the last hundred years and they haven't a clue why you're important. To 
make matters worse, the Factors are his priesthood. There is a prophecy as 
old as the ruined cities about an Enemy hidden deep within the planet. You 
have one chance to discover the last remnant of the ancient Builders and 
the evil that destroyed them long ago.

In the trackless ruins you'll find deadly weapons from humanity's past and 
eldritch devices to unlock your own latent powers. But you'll need more 
than firepower to survive. Story-driven gameplay, intelligent characters 
and cinematic cut-scenes make knowing your allies as important as blasting 
your foes into the next life.
