I never played the game, but I watched a walkthrough
In the version I saw, the main characters had their weaknesses, but struggled through them to help others. Ethan Mars goes to extreme lengths to help his son, Madison Page sacrifices a lot to help Ethan, Norman Jayden gives up his drug addiction to help find the killer, and Scott Shelby goes out of his way to protect a prostitute and a cashier who's being robbed.
It plays out very similar to a movie. there is a dramatic beginning, opening titles, rising action, a definite climax, and then a satisfactory conclusion. The plot is about an attempt to save a young boy's life and stop a serial killer, so the messages are positive. The content, however, is major red flag for some ages.
(NOTE: all the content below is taken from the walk-through that I watched; thus, there may be more or less, depending on the choices you make)
Drug Content: Moderate-6/10
Norman Jayden is addicted to a fictional drug. He takes two trips, and is tempted to do so other times. We see him experiencing some negative consequences as a result, including hallucinations and blackouts.
About 50-100 profanities in all. Some uses of f*ck(including a couple combined with "mother"), as well as sh*t, and other milder language.
Sexual Content: Major-7/10:
Ethan is seen nude in the shower(we see bare buttocks, but no full frontal nudity). Madison is forced to strip down to bra and panties by a thug with a gun. She is also assaulted by several rapists, who briefly paw at her torso(she's wearing panties and a tank top). She's also knocked out by a elderly doctor who then slowly runs his hands along her body(his doesn't last long). Shelby enters a prostitute's apartment, and she references sex, but this doesn't go anywhere.
Shelby, Madison, and Jayden gets into several brawls, punching and smashing opponents. Ethan also injures himself multiple times(we see violent wounds after a car accident and again later when he crawls over glass). There is one extended shootout, with at least a dozen gunmen taken down. The most disturbing violence includes a boy and a woman(separately)getting drowned. One man shoots another point-blank in the head(execution style). The most graphic moments are when a man is run over by a big truck and we see a blood puddle, as well as when a woman stabs an old man in the heart with a drill(he falls on her, adding to the disturbing quality). Also well worth noting is a scene in which a character has to cut off his finger. He grabs his little finger with pliers, and after a long build-up, slams his fist down on them, crushing and cutting his finger off(the impact is felt, but not shown).
In summary, great game for mature audiences.
