Gordon Freeman was originally a researcher for the military (didnt you know that?). His first assignment took him to the Black Mesa Research Facility. His expertise was required for a "situation" that was developing there. Within 2 hours, Freeman was on a transport helicopter heading for Black Mesa.

Little did he know what horrors would await him...

This series of SP maps is based on the Spirit of Half-Life DLL, so it comes as a sort of "mini-mod". Everything you need to play is included.

To install: Create a folder called Bigsci in your half-life folder, and unzip the files into there. I dont want any more ppl overwriting their HL intallation!
