This is a Source engine remaster of an old Half Life 1 mod called "Unknown Faction." The mod is shorter with 9 maps, but hits all the major sections. Credit goes to Crowbar Collective and all the creators of Black Mesa Source for their free version here on ModDB; I'm using many of their textures, models and enemy AI. Unknown Mission takes you back to Black Mesa for a quick job. The ultimate goal is to back-up some critical files to an offsite location and then leave. Think, run, shoot and live your way through each section with automatic sentries, broken industrial areas on fire and the military presence.
