Sources and Evidence
Every factual guide page names the sources that support its main answer. This page explains which sources carry the most weight and where the current evidence stops.
Inventory checkedLast review: 27 Aug 2026
Evidence Levels
| Official primary | Official game site, system pages, producer letters, storefront facts, and official announcements. Used for game mechanics, modes, dates, platforms, and languages. |
|---|---|
| Released-game observation | A result that can be repeated in the same game build. It must name the version and test conditions. No page currently presents a released-game test as complete. |
| Independent cross-check | Reputable reporting can confirm an announcement or explain context, but it does not override the current official source. |
| Platform support baseline | Steam or a platform holder’s published troubleshooting sequence can support general PC checks. It is never presented as proof that a specific BRIGANDINE ABYSS bug has a confirmed fix. |
| Community question | Reddit, forums, videos, and comments help identify what players need. They are not treated as proof of a mechanic without verification. |
| Unverified | Specific levels, full data tables, formulas, or claims that the available sources do not support. These stay labeled or withheld. |
Core Official Sources
- Official game site — news, platform information, and primary navigation
- Official Introduction — setting and six Story factions
- Official Characters — broader official roster and individual profile directory
- Official System — campaign loop, units, combat, growth, and Class Change
- Steam store — release date, languages, PC requirements, and product features
- NIS America — current publisher platform list
- Nintendo of America — Nintendo Switch 2 digital listing and regional date
- Steam Community — official announcements and producer updates
- Steam Support — general Windows steps when a game does not launch
- Producer letters — detailed pre-release system examples
Release-State Check — 27 Aug 2026
| Steam PC storefront | Steam lists the PC edition as released on 26 Aug 2026. |
|---|---|
| Official Japan product page | Happinet lists 27 Aug 2026 on its Japanese product page. Storefront and regional dates are kept distinct. |
| What this check supports | Product availability and the site’s retail-release label only. It does not prove an individual guide claim, a bug report, or a full walkthrough. |
Known Evidence Gaps
- Complete class tree and exact Class Change requirements.
- Complete lists for Mission nations, monsters, Support traits, equipment, and objectives.
- Released-game damage, hit-rate, terrain, and difficulty formulas.
- Patch-specific fixes and reproducible troubleshooting after launch.
These gaps are not filled with data from older Brigandine games. A page is updated when a new official source or repeatable versioned current-build test closes the gap.
Corrections
If a cited page changes or a guide conflicts with the released game, use the source links on that guide to identify the exact claim. Corrections should include the page URL, the sentence in question, the game version if relevant, and a public source or repeatable test.
