Enigma mod for Half-Life

Enigma, is a mod for HL1. The main storyline to Enigma is a teleporter has been built for long distance traveling, and your job is to use this teleporter to go through a series of challanges. Every challange will have a differnt envioment to it, with high detail, and enemys throught the challange. Before going through the teleporter, the player will first realize they are in black mesa, as this will take place before, and during the incident. Currently Enigma is rather new, but wont take years to finish, possibly only months. As for if this will use the normal HL, or Spirit, is unsure.
