From the official website:
“heXen:Edge of Chaos will be a new and free game, based on the original Hexen game which was developed by id Software and Raven Software. Edge of Chaos is being developed by a team of fans who have always loved the original Hexen since it came out. When id Software released Doom3, we immediately saw immense potential in the engine itself; the ‘Hell’ maps gave us the inspiration to make a hack-and-slash game based, primarily, on the original Hexen.”
