Half-Life Featureful SDK 2026-07-17

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.

Changelog

Bugfixes

• Fixed ideal yaw for rappelling monsters who come from repel entities. They used to have wrong head turnings after landing because of that.
• Fixed vortigaunts dealing damage to themselves with a coil attack when certain relationship classifications are set (e.g. Alien Monster). Thanks @lazy-paperboy for reporting.
• Fixed handling custom punchangle roll in trace_hull_attacks.

Monster changes

• Implemented smoother landing for rappelling monsters (coming either from repel entity or from osprey). Sometimes monsters were in "rappel" state longer than needed. Thanks @nreaLms
• Removed the limit on the maximum number of civilians (scientists, security guard) who can follow the player at the same time. It used to be 4. Now it's unlimited, like for Op4 marines and other following monsters.
• Set the default delay between monster's pain sounds to 0.25 (instead of 0) to prevent pain sound spamming caused by some monsters.

Entity templates

• Renamed touch_attack to leap_attack. Added more properties, for defining jump distance, height and punchangle on the attack hit.
