Credits & sources

BattleStudio is an independent creation: our army builder, validation engine, and product experience are original software we designed and built ourselves. We are not a fork, reskin, or rebrand of another army builder.

The projects and publications below are sources we respect and use as reference and comparison material while developing and certifying what we make — so our lists stay aligned with the wider Old World ecosystem. Where open-licensed datasets are adapted into our schema, we say so clearly and give credit. None of this implies affiliation with, or endorsement by, those projects or Games Workshop.

Official rules references

For list-building and special-rule wording we treat Games Workshop publications and the Warhammer: The Old World Online Rules Index as the primary authority when available. If BattleStudio and an official source disagree, the official source wins for play.

Special thanks to the Online Rules Index, whose integration enables descriptions of the special rules.

Old World Builder

Faction dataset structures and technical list-building values (unit/option trees, costs, and related composition data) are adapted from Old World Builder, an open-source project developed by Nico Thiebes and contributors, licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). Material from upstream v2.2.7 is modified for BattleStudio’s schema, IDs, validation, and product needs. Old World Builder is unofficial and not endorsed by Games Workshop Limited. Live tool: old-world-builder.com.

A big thanks to the OWB Discord community and everyone who entered records, reported bugs, translated, and generally provided feedback — without that support, Old World Builder would not have been possible so quickly and to this extent.

Icons

Fantasy icons from game-icons.net (CC BY 3.0), including faction marks adapted via Old World Builder’s army-icon set. BattleStudio uses them as monochrome masks. List playstyle marks are original BattleStudio silhouettes in the same treatment.

New Recruit

Special thanks to Vincent Massias, creator of New Recruit, and to everyone who maintains that platform. New Recruit is one of the community builders we use as a comparison reference when certifying and stress-testing BattleStudio. It remains an independent project — this is gratitude and acknowledgement, not affiliation or shared ownership.

Players & reporters

BattleStudio exists thanks to players who build lists, spot mistakes, and send careful bug reports. Community feedback is one of the main ways we keep costs, options, and rule text improving for everyone.

Accuracy

We aim for rules, options, and points to be as reliable as possible, but BattleStudio is not a substitute for official publications or your event pack. If anything looks doubtful, verify it before you play — and tell us if you find a mismatch.
