Watch on YouTubeHow to read the available evidence
NEKCOM published an official hands-on demo guide before the show. Its footage moves through story combat, the RV camp, Neo Yokohama exploration, and a boss encounter. These scenes describe the event build; they are not a promise that the same content will appear in a later public demo.
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.

GAME Watch — Gamescom hands-on report: A dated report used for what its writer saw or recorded; preview-build observations are not final specifications.
Steam — Showa American Story: Current store record used for availability, platforms, and specifications; it is not proof of unannounced features.
