Island Command includes a browser port of Advanced Strategic Command (ASC) and a separate, simplified Classic skirmish game. ASC is copyright Martin Bickel and its contributors. Original authorship and license notices are retained.
ASC and our browser bridge, game interface, and Classic rules are provided under the GNU General Public License, version 2 or any later version. You may use, study, modify, and redistribute them under that license. They come without warranty, including any implied warranty of merchantability or fitness for a particular purpose. Third-party components retain their own licenses.
Source is available here alongside the game, without a separate charge. These files include the editable code, original artwork and definitions, browser patches, build scripts, and dependency sources needed for rebuilding. Download all four ASC data archives to restore its complete data folder.
The native source archive explains how to assemble the downloads and
rebuild with Emscripten 4.0.15. It includes the unmodified upstream source
and dated browser modifications from September 6–7, 2026. ASC revision:

LGPL library sources, their changes, and the source of the application that uses them are supplied so you can modify those libraries and rebuild/relink the game. No separate restriction on modification or reverse engineering for debugging those changes is imposed by this project.
Game artwork and campaign data are taken from the GPL-distributed ASC project. Component-specific notices, including the font license, take precedence for those components. The native renderer uses ASC artwork directly; Classic converts selected PCX images to PNG, recolors player palettes, and adapts terrain and facilities. Original files and conversion scripts are supplied.
This software uses the FreeType Project and is based in part on the work of the Independent JPEG Group. Their notices are included in the native notice collection.
Battle Isle II screenshots informed the visual direction. They are not included as game assets. No commercial Battle Isle game files, campaigns, music, or logos were deliberately copied into this distribution. Battle Isle and Blue Byte names belong to their respective owners; this project is not affiliated with or endorsed by them.
Keep copyright and license notices, mark your changes and dates, and provide the corresponding source and build materials for the version you distribute. Preserve the separate dependency licenses. Public hosting preserves recipients’ rights under its open-source licenses.
Licensing package reviewed September 7, 2026. Source downloads must be refreshed whenever the game or its dependencies change. This page records the implementation and provenance checks; it is not a legal opinion or an independent clearance of every upstream contribution.
