Details

Overview

Dark Dice: Cthulhu Investigation Log plunges players into the chilling depths of Lovecraft's Mythos, offering a dice-driven investigation experience where every decision carries significant weight. Developed and published by Selig Interactive, this RPG-infused adventure game invites you to manage an Investigation Team from your Society's Headquarters. From there, you'll dispatch investigators into seventeen distinct, standalone cases, each set within iconic Cthulhu Mythos locations like the Mountains of Madness, The Colour Out of Space, The Dunwich Horror, and Innsmouth.

The core gameplay loop revolves around reading case files, carefully weighing the risks involved, and committing to a path. Once an investigator crosses a certain threshold, there is no turning back; the only outcomes are escape or succumbing to the horrors that await.

The investigation mechanics are designed to mimic the tension of real Cthulhu-style TRPGs, with checks drawing upon character stats rather than predetermined outcomes.
