Half-Life: Source
From HalfLife 2 Knowledge Base
Description
Half-Life: Source is Valve's port of the original Half-Life to the Source engine. The port was performed by Valve to test what porting content over from the HL1 engine would be like. It is mostly a direct port and uses the original textures and models. HL:S inherits features from the Source engine such as reflective water, improved lighting, shadowing, improved texture filtering, 3D skyboxes, chapter selection, 3D menu backgrounds, rigid-body dynamics, and ragdolls. Physics manipulation is limited to the original capabilities as to not affect gameplay. An attempt to recreate to the the original Half-Life with improved content is underway called Black Mesa: Source.
