Lifeline is a text adventure, but one with a serious difference and much higher stakes than you might be used to. You're not the protagonist of the story... and your decisions could get the protagonist killed.
Taylor is the sole survivor of the crash of the Varia, on a barren moon somewhere in the vicinity of Tau Ceti. Reaching out on comms, Taylor is able to find a single person, a single lifeline. You. As Taylor sets about exploring the inhospitable environment, you'll help make decisions on what to do next. The troubling part is that none of the decisions are good ones and one wrong move could land Taylor in serious trouble.
The mechanics are what set Lifeline apart. It plays out in real time, notifying you via your phone's alerts, through which you can also respond to and interact with Taylor, making this the first mobile game that I know of that can be played via the lock screen. It's also compatible with the Apple Watch, where you can receive notifications when Taylor is ready to talk.
And it's surprisingly heart-wrenching as you start to develop a connection with Taylor, knowing that hope for survival is, at best, slim.
