Half-Life Featureful SDK 2026-07-14

This release includes:

• The mod sample with all needed assets and demo maps.
• The dev-only package that includes only updated game libraries and FGD.
• The apk for Android (you'll need to manually put the featureful mod folder in your Android Xash3D-FWGS installation)
• Custom FGD provided by the community with related assets (like entity-specific icons and models) that might help the level designer.

Note: zhlt entities are not included in the FGD. You must add zhlt.fgd to your game profile configuration in the map editor.

If you already have a mod in development based on Half-Life Featureful read this article to get the idea how to apply the new SDK version for your project.
