|“||I can show you the truth. But you must shed some blood.||”|
— Jigsaw introduces Campbell to his game[src]
The primary victim of this game was Campbell Iman, a drug addict and terminal cancer patient, who had abandoned his own son when he was still a child. Therefore, he was ultimately targeted by John Kramer, better known as the Jigsaw Killer. After abducting him, Jigsaw or one of his accomplices took him to an abandoned railway building, where they had set up a deadly game for him. While Campbell was still unconscious, a key was surgically implanted behind his right eye. Additionally, a strange symbol was carved into his chest. Afterwards, a mechanical device, a Death Mask filled with sharp and pointy nails, was locked onto his body and he was placed on a chair in the middle of a room.
|“||Hello, Campbell. I want to play a game. You flushed your own life down the toilet with your addiction to drugs. The sins of the father pass on to the son, who is also a drug addict. You no longer know if he is alive or dead. I can show you the truth. But you must shed some blood.||”|
— Campbell is introduced to his first test[src]
When Campbell finally woke up, he immediately panicked and tried to remove the mask with brute force. When he jumped up from the chair, a TV turned on in front of him. A mechanical ventriloquist puppet appeared on the screen. It confronted Campbell with both his and his son's drug addiction and their bad relationship, stating that Campbell didn't even know if his son was still alive. However, it also offered him to show him the truth about his son, but only if he was willing to play his game.
As the TV turned off again, Campbell saw an x-ray of his head on the wall. Realizing that the key to the mask was hidden behind his eye, he immediately grabbed a scalpel from a small table in front of him. Despite the great amount of time and the mask's timer, which constantly ticked down, Campbell tried to stay calm and slowly cut open the scar right below his eye. Eventually, he ripped the key out of his wound and freed himself from the mask, only seconds before it slammed shut. (Saw II: Flesh & Blood)
In an attempt to find a way out, Campbell quickly calmed down and tried to find the exit. As he entered the next room, he saw the words "Now is the time to take a hard look at yourself" written on the wall. Additionally, there was a heavy metal door with a strange lock consisting of multiple dials with symbols drawed on and the words "Look around" next to them. As Campbell followed the advice, he saw himself in a mirror on the wall and was shocked when he noticed the symbol carved into the skin of his chest. However, he understood the true meaning of the clue and was therefore able to open the metal door by turning the dials until they fit the symbol on his flesh. (Saw II: Flesh & Blood)
|“||Light has the power to reveal what is hidden. But relying on it will obscure the path.||”|
— Jigsaw's next clue for Campbell[src]
In the next room, Campbell found a flashlight on a small table. As he picked it up, the face of the puppet appeared on multiple TV screens around him. The puppet told him that the light could reveal to him what was hidden, but warned him that relying on it woud "obscure the path." Campbell attached the light to the leather harness he was wearing and looked around the room. Thereby, he noticed a chart with the message "You can see, but do you understand, Campbell?" written on it. As he turned off the flashlight, the numbers 573 suddenly appeared on the chart as they had been written with a special fluorescent color and were only visible in the dark. Upon finding this clue, Campbell opened the next door, which was secured by a combination lock. (Saw II: Flesh & Blood)
In the next room, he saw that one of the walls was severely damaged. By using a heavy pipe from a nearby table, he destroyed the wall and thereby opened a new passage. After passing it, he saw through a window and witnessed another man, who was trapped there as well and tried to go through a door. However, as he opened it, a large scythe swang down from the ceiling and impaled him. Terrified by this, Campbell went on. As he did, he saw another panicked man, who ran away from a mysterious hooded figure. A few moments later, he witnessed a third man on the floor behind a fence. However, the man lost his consciousness shortly afterwards when he tried to crawl forward. Unable to reach him, Campbell continued his path and thereby noticed the words "History repeats itself?" written on a wall. As he opened the next door, another scythe swang down, just like the one which had just killed one of the other victims. Campbell however was able to evade it quick enough and therefore remained unharmed. Seconds later, he realized that he was in the same hallway as the last man he had seen. However, as he approached him, the man regained his consciousness, but was then dragged into the room behind him by another person with a pig mask. (Saw II: Flesh & Blood)
|“||Here is a bullish man, who has his own test. He will try to eviscerate you with brute force. Try to stay out of his way. You cannot stand against his strength, but no man can defy gravity.||”|
— Jigsaw tells Campbell how to defeat his attacker[src]
As the door slammed shut behind the man, Campbell was unable to follow him. Therefore, he turned around and went the opposite way. Upon leaving the hallway, he found himself in a small open area. As he looked around, he saw the warning message "Watch your step" written on a wall above an elevator. As he pressed the button to call it, the doors opened and revealed another one of Jigsaw's victims. The man wore a cage-like device with several pointy spikes on his head and had his hands tied up behind his back. Another set of TVs turned on, showing the puppet. It warned Campbell that the man would try to kill him and that he couldn't stand against his strength. However, it also told him that "gravity" could help him to defeat him.
As the TVs turned off, the man immediately charged at Campbell in an attempt to kill him with the spikes of the cage device. Even though Campbell tried to convince him to stop, the man repeatedly attacked him. Therefore, Campbell pressed the elevator button and opened the doors once again. When the man ran towards him again, Campbell quickly evaded his attack. Unable to stop soon enough, the attacker ran right through the open doors and fell down the elevator well. (Saw II: Flesh & Blood)
|“||Your persistence is not surprising, Campbell. I know that you have cancer. You do not have long to live. You came here searching for the truth about your son, to spend you few remaining months with him. The truth is this: he is alive. He has passed his test. Now you must make a choice.||”|
— Jigsaw tells Campbell about his son[src]
Following the man's death, another door was opened. Campbell went on and progressed through several hallways. As he finally went through another metal door, he witnessed the pig-masked figure once more behind a fence as they dragged away the body of another victim. At the same time, another set of TVs turned on in front of him. Jigsaw's puppet revealed the killer's knowledge of Campbell's cancer disease and his attempts to find his son. As promised, it told him the truth about him. Campbell's son was indeed still alive and had passed his own test. However, Campbell himself had to face one final task.
|“||Above you is another of my subjects. He is about the same age as your son and you have never met him. But he has a long life ahead of him. The glass elevator at the end of the hall will only fit one. Now you must make a choice. Save yourself and watch someone die or sacrifice your life for his. Let the game begin.||”|
— Campbell is introduced to his final test[src]
Another door was opened next to Campbell. As he went on through a dark room, the door slammed shut behind him and the lights turned on. Before him was a gaping chasm with only a single wooden beam leading to the other side. The last TV turned on and introduced Campbell to his final test. On the other side of the room was a glass elevator, which fit only one person. However, somewhere above Campbell's position was another victim, Michael Tapp. Campbell and Michael had never seen each other, but Michael was about the same age as Campbell's son. Campbell now had to make the choice to either sacrifice himself for Michael or to try to save himself. Depending on the player's choice, there were two different outcomes:
- Path of Flesh: As the TV turned off, the walls and the ceiling of the room started to move towards each other. Campbell was unable to reach the elevator, either because he chose to save Michael or because he wasn't fast enough. Eventually, he was crushed by the walls and died immediately.
- Path of Blood: As the TV turned off, the walls and the ceiling of the room started to move towards each other. Due to his desire to see his son once again, Campbell walked over the beam and thereby reached the elevator in time. As it went up, he saw Michael, who desperately tried to enter the elevator. However, he was crushed to death by the ceiling right in front of Campbell's eyes. As the elevator went further up and finally reached its destination, the door opened. Another metal door next to him opened as well, revealing Jigsaw, who had already waited for him. He revealed, that Campbell's son was alive and unharmed and offered him the chance to leave the building to see him. Campbell however was furious and charged at Jigsaw, yelling that he couldn't let his son live in a world with people like him in it. Jigsaw however evaded his attack and Campbell was impaled by a scythe swinging down from the ceiling. As he died, Jigsaw ended his game and remarked his failure with the words "Game Over." (Saw II: Flesh & Blood)
- While this has to be confirmed yet, it is possible that the key to the Death Mask, which was hidden behind Campbell's eye, was placed there by Dr. Lawrence Gordon.
