Process of Elimination ~ Platinum Guide

Quick Overview

If you are coming from Danganronpa, Process of Elimination will feel like a familiar, darker cousin to the series you love. It trades the high-speed Class Trial debates for a tense, cerebral, and highly tactical murder mystery. Process of Elimination is a brutal, high-stakes mystery that prioritizes logical deduction over fast-paced action. It offers a sophisticated take on the "Locked-Room" subgenre, where your primary weapon isn't a silver tongue, but your ability to organize and utilize a massive, diverse team of investigators under extreme pressure.
