BLACK MESA: Biodome

I highly suggest to turn the music on for a better experience as the map features some original Black Mesa and Half-Life soundtracks, voicelines and sounds!

WARNING: do a \MAP_RESTART to restart the level.

Black Mesa Research Facility, New Mexico, USA.

Play as 4 Hazardous Environment Combat Unit marines, who have been sent by U.S. government to cover-up the resonance cascade incident occured in Black Mesa, which allowed an intelligent entity from another world to keep a cross dimensional rift open in order to cause an alien invasion on Earth. Survive and escape the facility!
