More about Mycopsychosys: Project Jupiter

Mycopsychosys: Project Jupiter is a narrative-driven game where players explore and survive a deadly infection outbreak. As Hugo, a new recruit at the Plague Control Department (PCD), players alternate between office-based investigations and high-stakes field missions. The game features non-linear storytelling, environmental exploration in contaminated zones, and interactions with a cast of eccentric characters. Players uncover a conspiracy behind the infection while balancing bureaucratic challenges with survival threats. The core loop involves gathering clues, solving mysteries, and progressing through both office and field scenarios to reveal the infection's true origin.
