You play as Thomas Redgrave. A scientist working in Area3 Research labs. The story is parallel with the events in Black Mesa, the same day when Gordon Freeman and Scientists in Sector C started the whole event. INSTALLATION: You need to have HALF-LIFE installed on your STEAM (original half-life, no half-life:source or Half-life2). Run it at least one time. Install BraveBrain v1.1 to your STEAM/steamapps/common/Half-life directory and restart STEAM.
Incredibly lame storyline, quirky and mostly awful mapping and gameplay tactics, and hilariously bad voice acting to boot. There is still some fun to be had here however, but with many of it's cons, it outweighs the pros. Avoid this one unless you're really really bored.
