Direct answer
An official-game X profile advertises a Discord, and a Top.gg directory entry labels a NEKCOM Games server as official, but a stable first-party invite URL could not be extracted during verification. Treat the directory link as a lead and confirm the destination through @NEKCOM_SAS before joining.
What official sources confirm
The official X profile references Discord; Top.gg carries a matching server directory entry.
How to read the available evidence
A directory's “official” label is not equivalent to a developer-owned link. Invite URLs can expire, redirect, or be copied into impersonation pages. Before authenticating, scan the server name, owner information, linked official accounts, and destination domain; never send payments, wallet credentials, recovery phrases, or account passwords to unlock game access.
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.
Showa American Story — Official X: First-party material used for the claim it directly names; pre-release details can still change.
Top.gg — NEKCOM Games directory entry: Secondary community record used only for community status; ownership, permanence, and official endorsement remain subject to verification.
Still pending
Permanent invite URL, current owner, moderation status, official game-specific channels, and rules.
Pending details are not filled with guesses. They will be updated only when a traceable official source appears.
