Source: HalfLife2.netHalfLife2.net reports about a great sounding Half-Life remake for the Source engine that is being set up by jheaddon from their forums. The mod will be a complete remake of the original game, here some words:
The plan is to remake HL1 completely from scratch, rebuilding and improving on everything. Xen will be completely biomechanical and the other locations will be familiar but they'll be made more realistic. It wont be a simple change textures and models - every single bit of it will be remade to the best of Source's abilities.You can read up on his progress here, help out here and also check some great looking concept art pieces here at HalfLife2.net.
