Lunacid, a first-person RPG inspired by the King's Field series, was released in 2023 by Kira LLC. A prequel titled Lunacid: Tears of the Moon is set thousands of years before the original game and was developed using the Sword of Moonlight toolset. The game features user-generated dungeon crawlers and has drawn comparisons to atmospheric exploration titles like Thief and System Shock. Players engage in melee combat without blocking or dodging options, and character progression occurs automatically upon leveling up. Mana regenerates through successful melee attacks, and health is fully restored at the home base. The game lacks a tutorial, prompting players to refer to a classic-style manual. Players must locate five shards of a legendary sword while navigating a world filled with secrets, including hidden doors and challenging enemies.
