You are Gordon Freeman. On your quest to the Lambda lab you find another one of Black Mesa’s nuclear weapon storage facilities. This one is different though; a rogue group of military has stormed the building and plans to detonate the weapon to rid earth of the alien invasion. You, becoming aware of this, must deactivate the nuclear device to save innocent scientists, and to prevent the destruction of Black Mesa’s vast amounts of data, research and information.

This was originally created by Derek 'Hellfire' McBurney (see his readme for contact details).

Wow. This looks really dated by today's standards of GoldSource modding. Then again, so does the original Half-Life maps. :P

Nice mod from the early days. Ending trigger didnt work for me (mentioned in readme too) And the beginning of the Xen was strange, didnt have any idea what to do.. Had to check walkthrough for that, heh.

Would be nice to see this as Svencoop co-op mappack.
