Half-Life 1: Ray Traced - Release Trailer

Half-Life: Echoes is a Half-Life modification that lets you experience the events of the original game from a different perspective while improving graphics and animations. You play as a scientist codenamed "Subject #12" who arrives at the Black Mesa Research Facility on the day of the disaster. Now his main goal is to survive amidst the chaos.

A fan-made project reimagining the classic game Half-Life as a twin-stick shooter built on the Unity engine. The game offers a fresh take on Gordon Freeman's adventure in Black Mesa, introducing new elements such as enemies, weapons, support for custom campaigns, and more.

ERROR is a horror mod for Portal that transforms familiar test chambers into an unsettling and distorted space. The mod barely changes the puzzles, but adds darkness, glitches, eerie sounds, and unexpected scenes — creating the feeling that something is seriously wrong with reality.

TiR Tweaks is a collection of small improvements and fixes for Total Immersion Racing. Includes widescreen support, higher shadow resolution, increased draw distance, intro skip, and much more.

EDuke32 is a free, open-source engine and source port for Duke Nukem 3D, based on the Build Engine. It allows running the game and mods on modern systems, adding new renderers, improved graphics, scripting support, and extended editing capabilities.
