While The Invincible largely adapts plot elements, the setting, and more from Stanisław Lem's works and philosophies, it also introduces a new set of characters to provide a different perspective. In The Invincible, players will step into the shoes of Yasna as she attempts to rescue her crew after their crash landing on Regis III. For those familiar with Lem's work, the plot is very similar to the original novel, but developer Starward Industries has made plenty of changes in order to line it up with a game. One of those changes is player choice.
