The invincible is a narrative focused, first-person adventure game based on the 1964 sci-fi novel written by polish author Stanisław Lem. It immediately takes a detour from the novel and focuses on the crew of the Dragonfly, a research vessel belonging to the commonwealth instead of, like the novel, focusing on the crew of The invincible.

You play as space archaeologist Adie Ito, who has unearthed the ancient resting place of an A.I. god and onetime caretaker of the solar system known as Grace.

Responding to an unusual alarm call from a remote mining base, Jack arrives at the dark and desolate Fort Solis. With storm warnings imminent, he heads inside to make desperate contact. As the night grows longer, events escalate, spiral out of control and the mystery of what happened to the crew begins to reveal itself. The storms is approching, limiting Jack’s escape as he looks to hold out until morning arrives.
