Cinematic Mod (FakeFactory)
FakeFactory's Cinematic Mod is a modification which adds high-resolution textures to nearly all of the characters and objects in the original Half-Life 2 series. The mod replaces the original music with orchestral scores and also modifies weapon strength to resemble realistic stopping power.
As from version 5, this mod requires Windows XP (and up) 64-bit Opretion System. The reason of that is because the Source Engine limit in 32-bit systems is up to 2GB RAM use. After the engine passing this amount of RAM used, it's crashing.
