Simone Developer Lunarium Game Studio has announced that Lunarium, its upcoming atmospheric fantasy ARPG, will officially launch for PC via Steam on July 29, 2026. The announcement follows a series of community playtests that helped shape the final stages of development.
Set within a mysterious and poetic universe, the narrative follows Ave, a light-armored knight, and a mysterious traveler named Lune. Together, they journey across a fragile world where bubble-like realms rise from a chaotic sea toward a distant veil of stars, doomed to eventually burst in an endless cycle of rebirth and destruction. To save existence from collapsing, the duo must explore haunting, handcrafted environments – ranging from shattered kingdoms to mist-shrouded churches – to recover the lost glow of the stars and piece together forgotten memories.
Gameplay in Lunarium relies on strategic action combat heavily inspired by classic ARPGs, placing a strict emphasis on precise timing, parries, and counters. Players can leverage cooperative attacks and unique abilities by utilizing Lune’s assistance during battle. Character progression is tied to gathering “threads of hope” hidden throughout the world, which unlock new skills and magical techniques necessary to overcome formidable adversaries.
