With the advent of Source and release of Half-Life 2, VALVe has ported the entire Half-Life experience to the Source engine. The game now runs on the updated engine and uses all of the new engine's features. However, there is little in the way of true graphical improvement, as all the models, textures and sounds come from the 1998 Half-Life release.

Half-Life: Source is the original Half-Life on a new engine, with the same old looks and is no less appealing or well crafted as the original.
