"Back to the Primitive", the sequel to the popular "Operation: Firesweep" built for Half-Life 1, is a complete upgrade of the original mod to the powerful Source™ engine. "Back to the Primitive" seeks to retell the original storyline that took place in the dark war-zone of Black Mesa 5 years ago. You take the position of Corporal Shepard and fight your way through the detailed and damp atmosphere of the Black Mesa Research Facility. "Back to the Primitive" will feature a completely rebuilt Black Mesa, with the highest detail allowed by the Source™ engine. New models as well as all the original aliens will be featured in the mod, which will start development as soon as Half-Lie 2 is released. Most of the original development team is expected to return for the sequel. Check the site for more information, concept art and a detailed F.A.Q.
