Cthulhu Mythos RPG: Call of the Crystal Plus is a single-player indie RPG that blends mystery investigation with horror elements drawn from the Cthulhu Mythos. Players take on the role of a customizable protagonist who joins the Karasuma Paranormal Detective Agency to handle strange cases involving a mysterious crystal ball and other supernatural threats.
Gameplay
The core loop centers on exploring bizarre incidents alongside agency members. In the first chapter, titled The Call of the Crystal, the team investigates the origins of a crystal ball delivered to the protagonist while tackling additional odd jobs that arrive at the office. The second chapter, Eternal Sin, introduces new story threads after the group wins a hot spring trip, leading to fresh mysteries and encounters with different enemies. Combat occurs against grotesque beings, where player choices and companion bonds provide advantages in fights. Between investigations, time spent with allies strengthens relationships that directly influence battle performance. These bonds can develop into closer connections based on decisions made during downtime, potentially unlocking distinct conclusions tied to specific partners.
Character creation offers extensive options. Players select gender, age bracket from the 20s through 40s, name, base stats, and skills that aid in combat or social interactions. A Diagnosis Mode lets users answer a series of questions to generate a fitting avatar without manual stat allocation. Additional systems include a costume feature with unique outfits for each character, including yukata designs, plus dedicated interaction events that expand on individual personalities. New items added to the game further streamline progression and resource management during cases.
Game Modes
Two dedicated difficulty settings support broader accessibility. Casual Mode and Easy Mode both lower the challenge threshold while providing increased experience point gains. These options suit newcomers or players who prefer focusing on story and character interactions over demanding combat. The game remains a single-player experience throughout, with no multiplayer components.
Story and Characters
The narrative unfolds across the combined chapters, emphasizing teamwork within the paranormal detective agency. Companions each bring distinct traits that players can explore through repeated interactions. Fishing appears as one of the added activities in the second chapter, offering light side content during the hot spring sequence. A crossover event titled Sachiko-san of Happiness integrates elements from the horror series Corpse Party, providing extra scenarios for those familiar with that franchise.
Is It Worth Playing?
This title suits players who enjoy casual-paced RPGs that mix light investigation, relationship building, and horror themes without heavy mechanical complexity. The built-in difficulty options and experience bonuses make it approachable for first-time players or those returning to the genre. Customization depth and companion events add replay value through different relationship paths and endings. Those seeking straightforward single-player experiences centered on Cthulhu-inspired mysteries will find the combined chapters and added features provide a self-contained package focused on story progression and character moments.
