Half-Life, released by Valve in 1998, opened with a long tram ride through the Black Mesa facility, making rail travel and industrial ambience central to its identity. Fans later ripped and shared its train, tram, and machinery sounds on soundboards and in video edits, where they became shorthand for a gritty science-fiction journey. The clip still appears in gaming compilations, memes, and Half-Life tributes because that opening sequence remains one of the most recognisable introductions in first-person shooters.
