Direct answer
Steam currently lists 8 GB RAM, DirectX 11, and 50 GB storage as the minimum. The recommended entry raises RAM to 16 GB. The OS, processor, and graphics fields are still marked TBD, so a complete PC specification is not available yet.
What official sources confirm
Minimum: 8 GB RAM, DirectX 11, 50 GB available storage.
Recommended: 16 GB RAM, DirectX 11, 50 GB available storage.
A 64-bit processor and operating system are required.
How to read the available evidence
Steam marks the game as requiring a 64-bit processor and operating system and lists Windows as the current PC platform. It does not yet name a Windows version, CPU, or GPU in the requirements table. There are also no official targets for resolution, frame rate, presets, ray tracing, or Steam Deck performance.
The game has not launched. Trailers and developer interviews establish direction, but they do not guarantee final numbers, controls, optimal strategies, or content structure. This guide gives current NEKCOM and Steam pages priority; older announcements remain historical evidence and yield when newer first-party listings conflict.
How the sources were weighed
This page ranks evidence by how directly it supports the search question. Developer and official game pages establish the setting, platforms, and announcements. Steam establishes current PC store status and listed requirements. Community directories can show that a destination exists, but they do not replace a first-party statement.
Steam — Showa American Story: Current store record used for availability, platforms, and specifications; it is not proof of unannounced features.
Still pending
Specific OS version, CPU, GPU, performance targets, preset definitions, Steam Deck verification, and final launch requirements.
Pending details are not filled with guesses. They will be updated only when a traceable official source appears.
