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.
A very nice mod with some cool bits in it. The "vehicle" portion was awesome. I liked interweaving previously visited areas with new ones. A tad bit on the easy side but quite enjoyable. The axe was cool as well.
I did encounter one bug though. At the top of the flooded lift, the barrels are supposed to be moveable; mine were not. I could grenade jump into the vent but still...
