About this game
Jingjie: Probability Cloud - Nagumo's Dilemma is a Pacific carrier command simulation set against the carrier battles of World War II. "Nagumo" refers to Chuichi Nagumo, commander of the First Air Fleet during the opening Pacific War operations and the Battle of Midway. The game is not a biography or a celebration of any wartime regime; it uses this historical command problem as a frame for uncertainty, delayed reports, flight-deck pressure, and decisions made before the truth is fully known.
You do not pilot aircraft or command from a fully revealed map. You read contact evidence, judge confidence, age, and error area, manage carrier operations, and decide when an uncertain position is good enough to risk a strike.
The current Early Access build includes multiple authored scenarios, free play, and an endless sandbox. Its command surface routes contact evidence through launch readiness, air-group scheduling, and a professional combat workflow, while manual, semi-automatic, and bounded automatic control remain visible and interruptible.
Every report has age, error, and consequence. Scouts can find a possible carrier, lose the trail, return low on fuel, or deliver information that is already going stale. The opponent adapts to observable evidence and repeated habits without reading hidden player intent.
- Imperfect intelligence instead of an omniscient map.
- Carrier operations shaped by time, flight-deck capacity, CAP, scouting, recovery, and attack opportunities.
- A contact-to-strike path with visible confidence, readiness, scheduling, and workflow consequences.
- Manual, semi-automatic, and bounded automatic workflow control with visible safety constraints and manual intervention.
- Multiple authored scenarios, free play, endless sandbox, and after-action analysis for replayable command problems.

Camera Update | Switch Between 30° and Top-Down Views
The new default 30° 3D view brings the sea, clouds, and fleet into perspective. Switch to the 90° top-down view for route planning and tactical command.Where to switch: Click “3D · 30°” in the bottom-center battle-map toolbar to cycle through 30° → 90° → 12° Horizon.Camera controls: Mouse wheel to zoom; Alt + left-drag to rotate; middle-drag to pan; Shift + wheel to adjust CAP direction. C, by default, toggles cloud tactical-area outlines. Use the fleet-centering and full-map buttons to regain your bearings.WebGPU rendering, 3D clouds, sea and lighting effects, deck-operation displays, branching reconnaissance probabilities, and performance improvements remain experimental. Please report bugs in the Steam Discussions!

Development Log: Making Recon Missions Clearer and More Consistent
We reviewed recon objectives, continuous tracking, aircraft handoffs, report confirmation, and on-screen feedback. The main goal was to find confusing overlaps and conflicts between older and newer systems.This update covers the audit and improvement plan only. Gameplay and the Window Lab menu have not changed yet. Future updates will gradually make recon actions, intelligence results, and battlefield feedback clearer and more consistent.Read full article on Community Announcements (kkk)
