Tommy is a playable character in the game and is given more backstory in its continuity through the Tommy Jarvis tapes, collectible cassette tapes with audio of Tommy being interviewed, which bridge the gaps between films and the tapes take place before Tommy was called back to Camp Crystal Lake and battle Jason again.

They start with Tommy being questioned after he has killed Jason. It is revealed that his mother was in fact killed and that the authorities don't believe the killer was Jason Voorhees. He also claims to have made himself look like a young Jason to communicate an understanding of each other. He meets Detective Alex Rico, who is annoyed by the Jason claims and put off by Tommy's behavior. It is vaguely implied Rico came to Crystal Lake sometime after the urban legend of Jason came to be. He is assigned to child psychologist Lauren Marino, who makes friends with him and wants to help him. A year after being institutionalized, Tommy's sister goes off to college and he is transferred to Westin Hills Asylum for more intense treatment.

By adulthood, Tommy has been through four programs, having been kicked out of Westin, Smith's Grove, Glen Echo, and New Orlean Psychiatric, expressing depression over his belief that he'll never get better. Lauren sends him to the Unger Institute near Crystal Lake in the hopes that confronting his fear will help him, which he is reluctant of. Tommy is transferred to Pinehurst without Lauren's knowledge, her being notified after Joey is killed, with Tommy's presence at the time raising suspicion. Tommy meets Rico again after Roy's killing spree and death, refusing to cooperate since all the necessary information is apparently gathered. Tommy later tells Lauren his being moved to Pinehurst, closer to Crystal Lake, was his idea, thinking it would be more effective. He expresses the fear that he has become Jason and is dangerous, revealing he had a dream of killing Pam in Jason's mask. Tommy is moved back to Unger, where he meets Allen Hawes, who believes him about Jason and knows where he is buried. Lauren hopes that Tommy can see Jason was merely a persona, which he doesn't. Tommy reveals he and Allen are going to check Jason's grave to see if Rico's claim that he was cremated was true.

After Jason's killing spree after his resurrection, Rico returns, further frustrated to come across Tommy again. He goes on a rant about the urban legend, expressing his belief that all the murders were caused by psychos attracted by the story who took on the persona, and people like Tommy perpetuating the myth causes each new massacre. In a bit of humorous meta dialogue, he points out how the legend doesn't make sense, with Jason having died as a child, returning from the dead and suddenly being a grown man. He makes an implied threat on Tommy and an explicit threat on Lauren, who he is angry with for not having locked Tommy away to keep him quiet. This makes Lauren leave.

Lauren meets with Tommy, who tells her about trapping Jason in the lake, only for her to tell him that divers have been sent in and not found anyone. Tommy is outraged to hear this, believing Rico passed on false information, also angered that Jason was not in fact cremated. He expresses guilt over his hand in Jason's resurrection and subsequent murders. Lauren now expresses her own frustration over Tommy's "delusion" of Jason and refuses to believe he saw Jason rise from the grave, also agreeing that Tommy is at fault for attracting murderers with the Jason legend. The witnesses unfortunately only saw a man in a hockey mask. She tells Tommy she can no longer help him, which leads Tommy to believe she sold him out and "they" are going to kill him to silence him. He becomes hysterical and knocks out Lauren with a lamp before fleeing from the approaching police.

Tommy makes his own audio recordings, revealing he has created a conspiracy website about the truth of Jason and the attempt to cover him up. He is on the run, hiding from the authorities. His sister has stopped contacting him, which he says he forgives her for, believing she has been brainwashed as well and wishing her safety. He apologizes to Marino. He says he's tracked down one of the survivor's from his last Jason encounter, but stops when a police car passes.

In the final tape, Tommy says he has found a more secure location and the survivor he tracked down was Deputy Rick Cologne, who was apparently "gotten to", as he moved away to Ohio and changed his last name to his wife's maiden name of Pastori. Unfortunately, Rick was supposedly killed by a maniac named Pinker, though Tommy believes perhaps he was starting to talk and was taken out. He saw a news report of Jason's activities on Crystal Lake and a cruise ship as he intends to return to Crystal Lake to try and deal with Jason permanently. It is then revealed Tommy has been captured and locked up again under Lauren's watch, and is taken away in hysterics, begging not to be medicated and made to sleep, only to be sedated and sent to solitary. Lauren reveals Tommy has been allowed to record himself, during which he expresses his conspiracy beliefs, seemingly unaware of his current situation or in deep denial, operating under the delusion that he is on the run. (This opens the possibility that Tommy was captured very soon after fleeing and was never actually on the run). He is showing extreme fear of nightmares and needs to be medicated to get rest. She intends to watch him while he slumbers to discover how he is lacerating himself in his sleep. The tape finishes with the reveal that Lauren is looking after Tommy in Westin Hills.

My thoughts are it's nice they acknowledge what happened to his family and the treatment he went through. I still think that Meg would stand by him and he would live a better life after six. I think it's interesting they have Freddy tormenting him and it connects it with a nightmare on elm Street. He spends time in Smith's Grove connecting it to Halloween and making the character Jenny Myers related to him. The new Orleans connection places Vuctor Crowley into the mythos and suggests his dad could be Elis and they could be brothers.
