Half-Life Unified SDK is a project that aims to provide an updated version of the Half-Life SDK, with full support for the expansion packs Half-Life: Opposing Force and Half-Life: Blue Shift as well as new features.

Overview

The following types of changes are in scope for this project:

• Bug fixes
• Features to improve the game's code (refactoring, generalizing, simplifying)
• Fixing game-breaking bugs in game assets (e.g. soft-locked trigger setups)

The following types of changes are out of scope:

• Graphical upgrades
• Physics engine changes
• Other engine changes

Requirements

• Requires .NET Desktop Runtime 6 for the tools

Tools

Several standalone tools are branded as part of the "Unified SDK" project but are separate from the mod code.

• Half-Life Asset Manager, a more robust and more stable replacement for Half-Life Model Viewer.
• Half-Life Unified SDK Map Decompiler, a modern BSP decompiler with more accurate results than previous tools.

Quotes

Once the Unified SDK has been released i'm going to archive Half-Life Updated, Half-Life Opposing Force: Updated, Half-Life: Blue Shift Updated, and Half-Life Updated CMake.
