The Core is a total conversion single-player mod for Half-Life. Survive the disaster as Maurice Andrews, a low level engineer stationed in Black Mesa during the events of the resonance cascade. Seemingly trapped, Andrews must fight his way to the surface to survive.
This is the third and final version of the sections connecting the start of the mod and the lobby leading to the security complex. This section was origally a badly mapped and textured sloping hallway ending in an empty and pointless room. Now it's a fully functional warehouse, with freight lift and forklift access (although they aren't actually visible here.)
