A hardcover art book chronicling the development of the dark science-fiction time-looping rouguelike bullet hell adventure shooter! When Selene Vassos crash-lands on a mysterious alien planet while in search of a cryptic signal, she's made to face treacherous landscapes, hostile creatures, and a ceaseless time loop that returns her to the moment of her crash each time she would otherwise have died. This oversized volume collects concept art of the volatile biomes and terrifying enemies, as well as insightful commentary from the game's creative team.

After the spaceship Helios crashes onto a hostile alien world, Selene Vassos, a lone ASTRA scout, must fight for her life against the horrific hostiles that live beyond every shadow. Following a trail of distorted memories, Selene just needs to hold on long enough to track down the White Shadow signal. Mystery shrouds the world of Atropos, and she begins to wonder: will she find answers at the end of her journey, or is this nightmare inescapable?
