Cause of Death: Can You Catch the Killer? was a video game developed and published by EA Mobile for iOS and macOS devices on December 16, 2010, that was removed from the App Store in September 2014. While being almost identical in gameplay, the game is intended for a more mature audience than its companion game, Surviving High School, as the game revolves around crime and serial killers and their pursuit by law enforcement. The suggested age on the App Store was 12+. Cause of Death is a visual novel that is divided into a series of volumes, each of which is made up of eight chapters (excluding the first, fourteenth and sixteenth volumes). The base game (which was free from the App Store came with the entire first Volume—future content needed to have been downloaded either by "Episodes on Demand" or "Now Airing". The first 6-episode volume was released in December 2010, and the series released its final episode in July 2014, and the game was unlisted from the App Store in September 2014.

Development The game was conceived in 2004 as the first story game for phones; the concept was developed before a writer had joined the team. They found a student at Stanford, who began writing the game at nights after class. This would become Surviving High School, launched in 2005. The development team followed this up with Cause of Death, and later High School Story, Hollywood U, and Choices: Stories You Play, under the names Centerscore, Vivendi Games, EA, and Pixelberry Studios.

It usually took over a week to write each Cause of Death chapter, and because of this grueling release schedule the writing staff often had to work late (sometimes through the night), due to not wanting to disappoint their fans, who can "get restless when an episode is late, even by a matter of hours". When the staff discover that "a fan is excited about [their] stories or appreciative of [their] work" via Tumblr reviews or a Facebook comment, it "makes a big impact in the office", as it is a validation of their hard work.

When some of the writers work on the gruesome murders that take place throughout the series, they like to become fully immersed in their research, for example filling "[their] cubicle walls were covered in tarot cards and books about voodoo" when writing a psychic-themed episode." The game was a crime-based spin-off of Surviving High School. As many of the CoD writers also work on Surviving High School and switch between the two projects, there is a major contrast between the lighthearted and dark tones, particularly in the earlier years of SHS, which provides a nice change of pace and variety. Though originally Cause of Death and Surviving High School were constructed in two very different ways, over time SHS was altered to reflect CoD, becoming a more plot and character driven story rather and being directed at a more adult target audience. The Surviving High School visual novel engine was repurposed toward the gritty crime drama in Cause of Death. The art style also changed to become more realistic, expressive and gritty, and the minigame-style gameplay was replaced by an interactive movie structure. There has been at least one crossover between the two games, and some characters gave from one game have family members who are only present in the other game.

Some of the choices made by the writing staff have led to backlash by the audience. In particular, the Blaise-Jeremy pairing was seen as controversial to some, arguing that it is unrealistic and unwarranted, so the writers explained the rationale behind it: "There's something significant in looking at how opposites attract. You see it in real life all the time. Nice girls date jerks. Straight-laced guys go after free-spirited girls. Sometimes we're secretly looking for that person who will push us beyond what we're comfortable with...The BlaiseBird thing is all so refreshingly simple. I think Blaise was fed up with drama and just went for something she wanted, for better or for worse. Everyone else's love life on CoD is so pained and complex, so it's nice to have a romance that is so unromantic".

Writers for the series include Winchester, Georgia, Doc, Lily, Rasputin among others. They are hired due to certain talents while they stay away from other areas. For example, in the wedding episodes between Natara and Oscar, Winchester's role consisted on planning the "wedding-themed violence" in the action scenes, while Lily did some of the more "grace[ful]" writing. The kiss between Natara and Mal at the end of the episode was a tough moment to write that went through many drafts, as it was an integral "exciting" turning-point of the series. While "originally, it was a smaller, more subdued moment, just very warm, and honest, and intimate", teammate Rasputin argued "No. People have been waiting for this for ten volumes. This moment needs to be much, much bigger", so he added "more description, way more emotion [and] a gentle rain".

The game has both a frequently-updated Facebook account and a Twitter account in order to provide information about upcoming episode and other information related to Cause of Death or Surviving High School. Surviving High School (EA), Cause of Death (EA), High School Story (Pixelberry) set a rare track record of three games by the same development team entering the top 25 grossing chart.

After over years and 170+ pieces of content (much of which now is available as a bundle pack), the series ended in July 2014, and its finale announced the app will be removed from the App Store sometime. Just two months after game's finale was released, the game was completely removed from the app store.

Gameplay Written in second-person (where the player plays from the perspective of characters), Cause of Death is very passive and laid-back gameplay-wise; it is purely a Visual Novel with major elements of Interactive Fiction and classic Choose Your Own Adventure books. The game is focused on storytelling, with a character's dialogue (or narrative dialogue) appearing above background images which shift to fit the location. Tapping the screen moves the text forward, and eventually, the player must make decisions to say or do something—these are shown with multiple options on the screen, and the player must select one.

Most but not all decisions will grant the player Detective Points if the correct choice is made. During action scenes or important conversations, failing a certain number of decisions will result in the player failing or dying; when this happens, the game will show a non-canon death/failure sequence (some of which are actually quite detailed) before the player gets a Game Over, requiring a revert to the last checkpoint or a replay of the chapter. If the player got 80-100 out of 100 Det. Points, they will get a bonus scene (Volume 1 needed 500-600 Det. Points for all 6 chapters together and had only 1 bonus scene at the end if this was met). These bonus scenes "are usually just short scenes which show something about the story you wouldn't have seen otherwise. It isn't vital that you see them all, but it does give you a sense of achievement when you manage it".

The game is "packed with mystery and suspense", and is "aimed at adults, due to the graphic nature of the plot and occasional sexual references". It is "a bit like the “Choose Your Own Adventure” books, but on the iPhone".

Episodic Content System What distinguished EA's visual novels (this and Surviving High School) from others is the fact that their games released new content periodically. There are 2 ways to do this; Now Airing and Episodes on Demand. Up until July 2011, episodes were released weekly on Friday; this became weekly on Mondays from then until September 2013; episodes began releasing bi-weekly (first on Mondays later on Wednesdays) from then on.

When an episode was released on On Demand, the previous episode would become available on Now Airing for free (though only one Now Airing episode can be on an iDevice at once). So On Demand players would experience the story faster and could freely play their episodes at any time, but paid more. Now Airing players wouldn't pay at all, but they would experience their story much slower and only be able to play an episode a time.

Story Cause of Death has a plot inspired by crime scene investigation television shows and is based upon solving murder mysteries. Other prominent themes include friendship, love, trust, morality and criminology. The story takes place mostly in San Francisco, although some there are a handful of situations (most notably part of Volume 11, nearly all of Volume 15 and most of Volume 16)) take place in other areas. Most protagonists are members of the SFPD (including FBI Agent Natara Williams), whilst the antagonists are serial killers; a plurality of whom have unique MO's, victimologies, motivations and backstories (predominately of tragedy or abuse). Organized, financial and political crimes have all been featured at some point, and crimes that are correlative to the protagonists themselves also play a role in the game's storyline. In the earlier seasons (particularly the first), the game's storyline had a stronger focus on criminals and crimes rather than characters. However, as the game progressed, the SFPD members and their character development have become a much more prominent focus.

Volumes Volume 1 was available for free in the base game. The remaining volumes are available to purchase as a set at various prices.

The length date's listed here are in relation to their release on Episodes on Demand. Note that sometime after all 8 episodes are released On Demand, they become released as part of a volume set; the release dates here list from the first episode's release to the last episode's release. These dates do not take into account Now Airing or the Volume Pack.

Except where otherwise noted, all volumes have 8 chapters not counting interludes or short stories released within.
