Some levels have been remixed too, with redesigned, or in some cases completely new, puzzles and set-pieces. But everything is huger, more detailed, and more dramatic, with production values approaching Half-Life 2, which breathes new life into the Black Mesa Incident. You take the tram into work, watch in horror as the resonance cascade floods the facility with aliens, dodge headcrabs in the office complex, clash with the HECU Marines, deal with giant tentacles in the blast pit, fight through a warzone on the surface, navigate the radioactive Lambda Core, and finally visit Xen. Black Mesa sticks closely to Half-Life in terms of structure.
