Torture Chamber

You wake up in a dark room, locked in chains. In the flickering light you find out you're not alone. Through the bars you see torture devices, bloody body parts and your obsessed guard, a mutant half man, half robot cyborg. The same question runs through your heads. What is this place and how did you got in here?
The guard is about to leave, here's your chance! Untie yourselves, discover the place and know the secret experiment you're part of.
