Half-Life: Dreamcast — a PC port of the unreleased Half-Life version for the Sega Dreamcast console. This version differs from the original and the later PlayStation 2 adaptation: it features modified levels, unique NPCs and objects not found in other editions, altered difficulty levels, and numerous hidden references to Dreamcast.

Xash3D FWGS - a fork of the Xash3D engine aimed at improving compatibility, performance, and functionality for running GoldSrc-based games such as Half-Life and its mods.

Half-Life - Full Audio Remaster is a modification for Sven Co-op and the Xash3D engine, created to precisely remaster all low-quality sound effects and dialogues from Half-Life, Blue Shift, and Opposing Force. Monster, machinery, scientist, weapon, and even footstep sounds have been manually cleaned and restored to full 24/44.1 kHz quality.

Alternate Textures And Extras – a FlatOut 2 mod that improves gameplay and textures: adapts AI to the class of the selected vehicle, removes the yellow filter on tracks, and updates driver textures for more realism.

HD texture pack for the They Hunger mod. It updates character models, including zombies and NPCs, replacing them with highly detailed ones, improves the appearance of environments and interiors, and optimizes the visual style while preserving the original game's atmosphere.
