HL4K: RT Reloaded is a 4K texture pack for the XashRT engine (Xash3D branch with tracing support) that replaces the original Half-Life textures with highly detailed 4K versions and adds real-time ray tracing: dynamic lighting, reflections and shadows, while preserving the atmosphere and gameplay of the classic game.

Half-Life: Urbicide is a mod with 11 atmospheric maps for single-player gameplay. The events take place during the Xen invasion of Earth. You take on the role of Bruce, a warehouse manager trapped inside a building with a colleague, while his fiancée Rebecca attempts to rescue him.

Half-Life: Rally is perhaps the most unusual mod for Half-Life, which takes Half-Life to a completely new level — now instead of weapons, the main tool becomes a car and the ability to outrace competitors. The goal is simple: be the first to cross the finish line using speed, tactics, and strategy.

Half-Life: Blue Shift: MMod is an add-on that allows you to play the Blue Shift campaign with the enhancements and mechanics of Half-Life: MMod.
