or "The Boiler Maze" or "The Spear Cannon" or "The Steam Maze Trap" The third test takes place in the boiler room of the abandoned zoo. This test is supposed to show William how far a person will go to survive. As William enters the boiler room, confronted by yet another Jigsaw tape, he notices that his company's attorney, Debbie, is also present. Jigsaw informs William that Debbie has 90 seconds to find her way out of the caged maze beneath him and acquire a key at the end of the maze to remove the device strapped to her body. Should she fail and the timer reach zero, the device would fire a metal pipe into her skull, impaling her skull and killing her. Debbie does not make it in time, so the pipes rammed into her skull, brutally killing her.
Hello, William. You have seen the flaws in your policy, but what you have not seen is the extent some people will go to when faced with death. The lawyer from your firm has ninety seconds to cross this room or the device attached to her chest will discharge and pierce her brain. She will find that the journey across this room is filled with danger. In order for her to make it, you will need to be there for her and it is you who ultimately holds the key to her survival. When faced with death, will she have the skills to live? Let the game begin.
Jigsaw explain the rules
Debbie's shackles are released at the start of the timer and she begins to crawl through the caged maze, but is halted by the hot steam jetting from either side of the cage. William finds a lever for the steam valves, and pulls it, diverting the jets of steam away from Debbie's path and onto his body. He screams in pain as the steam scalds his arm, giving Debbie the opportunity to crawl through. Debbie eventually reaches the end of the maze with a few burns and learns from a series of x-ray films that the key to her device has been implanted in the side of William's torso. With the 90 seconds nearly up, Debbie grabs a circular saw and begins to violently attack William to saw out the key she desperately needs to escape. William manages to avoid Debbie's wild attacks, and the timer eventually reaches zero causing the rectangular device on her chest to click into position and shoot a sharp metal pipe through Debbie's head, piercing her brain. William then watches as her lifeless corpse falls down three levels to the floor. Noticing another arrow on the wall, William reluctantly follows it and finds another key held in place by a piece of string. He grabs it and continues on his way, unlocking another strap from his body.
