Lifeline (2015 video game)

Lifeline is a text-based adventure mobile game developed by Three Minute Games for iOS and Android. The player guides the main character, Taylor, through a texting conversation, to survive an unknown moon after their spaceship crashed. Lifeline was written by Dave Justus and published in 2015.

Gameplay
In the game, players interact by choosing from two different responses to help the main character progress in the story. Taylor responds in real time, taking a regular amount of time to respond after telling the player they are going to sleep, for example. Taylor takes time to complete tasks, and the player has to wait for their response, only seeing the text: [Taylor is busy]. Some decisions require looking up additional information, and if the player makes a wrong decision, it can cause Taylor to die. In the event that Taylor dies, the player can rewind to a past decision and try again. Once the game is completed to any ending (such as death), Fast Mode is unlocked, which removes wait times between messages.

Plot
The plot follows Taylor as he tries to find a way back home after crashing on a foreign planet that turns out to be inhabited by hostile, hive-minded parasitic lifeforms known as the Greens. Taylor must overcome natural and unnatural elements in order to manipulate the structures of the planet and call a spaceship to come rescue them. The game is played in real time as Taylor explores, sleeps, and interacts on the planet, so sometimes the player is left waiting for hours before they will hear from the main character again.

Characters
Taylor is the main character of Lifeline. Taylor is a sassy science student from Earth, acting as a Cadet of the recently crashed starship Varia. Taylor is resourceful with the material around them, and when in a stressful situation, resorts to quips and humour. As a part of the game, Taylor's gender is left ambiguous, leaving the player to decide.

The Lifeline is the character the player plays. The Lifeline is in constant communication with Taylor throughout the game. The player must decide whether to let them die or attempt to save them, using valuable resources. The Lifeline is connected to Taylor through a signal from their IEVA suit.

Captain Aya is the former captain of the starship Varia. Taylor finds her in critical condition after the crash.

Sequels

 * Lifeline 2: Bloodline (2015)
 * Lifeline 2: Bloodline follows a teenage witch, Arika Lanphear, who is trying to rescue her younger brother. Through the plot, Arika finds many magical objects to assist her in her mission. The Lifeline is connected to Lanphear by blood magic.
 * Lifeline 2: Bloodline was also written by Dave Justus.
 * This game introduces the feature of being able to give the player a name. Arika will respond in certain ways if a specific name is entered. Another difference from the first game is that when a player selects an option in the game, the actual message sent to Arika is different, sounding more natural and allowing the fictional conversation to flow smoothly.
 * Lifeline: Silent Night (2015)
 * Lifeline: Silent Night takes place shortly after Lifeline, following Taylor in another adventure fighting against the Greens. This game was released around Christmas time, and has a very slight Christmas theme.

Lifeline Universe
After the release of Lifeline: Whiteout 2, Three Minute Games introduced a new app, Lifeline Universe in 2017. This app hosts all previous Lifeline stories, and all new ones, as released. The new installments are written by established authors and contributors from the "Author Program", who have applied and partnered with the company. These new stories vary from being continuations of past series, to original stories. Stories are hidden behind micro transactions. So far, the app has only been released on the Google Play Store, and has a rating of 3.6. The Lifeline Universe Twitter and Instagram have been silent since June 29, 2018. In August 2018, Big Fish Games has noted in a Zendesk that they are still working on new content for players, but they soon followed up with another notice, announcing that the Lifeline Universe service would come to a close early November of the same year.
