You're part of a strange game, and your role in it is Floor Guardian. Once someone has entered your territory, they dare not leave it alive. You must guard the only way to the next floor - the lift.

A small icon appears on your wristband, and you know that someone has hit the motion sensors on your floor. You switch off almost all the lights, quietly lurk in the darkness, knowing the entire space by heart.

In one of the corridors you spot the figure of your new Victim.The hunt begins.
