This mod tries to bring to life the Half-Life 2 beta/leaked files from 2002 - 2003. It is a massive overhaul, completely altering things from graphics to gameplay. It is based off of many popular mods for HL2 including the Cinematic Mod. Note that it comes in two versions (both can be found here on GameWatcher), a low-D and a Hi-D version. This is the high Definition version.
