Mycopsychosys: Project Jupiter

What Mycopsychosys: Project Jupiter is

Project Jupiter is a top-down pixel horror RPG — and the prequel to DeltaCat Studio's 2023 visual novel Mycopsychosys. You play Hugo, a brand-new officer at the Plague Control Department: process cases in a small Spanish office, then head into the field chasing clues about a spore-driven infection the department has been "studying for a long time."

It launches in Early Access on October 5, 2026 with Chapter 1 of a planned 3–4 chapter story — a full chapter's main storyline, not a demo slice. If you like the Mad Father / Ib / Drizzling Rain school of horror — investigation, dialogue, puzzles, pixel art that knows when to stop being cozy — this is that lineage with a bureaucratic badge.

Before you buy

• Price: not announced — the store's Early Access notes say it rises slightly before each chapter release, so launch is the cheapest it will ever be.
• Platform: Windows PCs via Steam. No console version announced.
• Demo: planned; a Steam listing exists but is not live — the release page flags it the moment it ships.
• Languages: English at launch; translations planned (the VN picked up French, Korean and Russian later).
• Length: Chapter 1's main storyline only — no secondary missions yet. Full version targeted 2027–2029.

What to do first

1. Wishlist it and buy at launch if price matters — it only goes up from here.
2. Skim the PCD survival rules — the game's own briefing; it makes the story click faster.
3. Decide on the visual novel — the series recap covers what the $5 Remastered VN adds. Optional — but it makes Ray and Onna hit harder.
