MIT is mentioned in the computer games "Area 51" (1995), "Half-Life" (1998), "Half-Life 2" (2004), "Metal Gear Solid" (1998), and in the "Fallout" series (1997–2015). In the case of the "Half-Life" series, the main protagonist, Gordon Freeman, is an MIT graduate and has a PhD in Theoretical Physics. The Infocom game "The Lurking Horror" (1987), written by MIT alumnus and interactive fiction pioneer Dave Lebling, is set on the campus of the George Underwood Edwards Institute of Technology, which strongly resembles MIT. Its fictional culture also parodies the MIT culture. For instance, G.U.E. Tech's class ring is known as the "brass hyrax", parodying MIT's Brass Rat. In the "Fallout" games, MIT is known as the "Commonwealth Institute of Technology". As nuclear war began, researchers from the university hid below the main building and continued with their research without making contact with other survivors. Eventually after many years, they took on the title of simply "The Institute", and became well known as a shady organization with extraordinary technology and the ability to create androids. The institute is featured as a major faction in the 2015 title, "Fallout 4". In , one of the main characters in the story is Edwin Robert House, also called Mr. House is a graduate of the institute, as stated in his obituary. The song and music video"MIT" by PomDP the PhD rapper  was released on May 23, 2020 and played during MIT's 2020 pre-commencement ceremony . The song and music video feature the contributions of a number of renowned alumni from MIT, including Richard Feynman, Patrick Winston, Isaac Chuang, Claude Shannon, Marvin Minsky, and Rafael Reif. The song introduces a new form of tech rap music, and was the first rap song to be featured in an MIT commencement. In the Broadway musical "Rent" (1996–2008), a major character, Tom Collins, is expelled from teaching at MIT, "for [his] theory of actual reality". The song "Etoh" by the electronic music group The Avalanches describes MIT as "the home of complicated computers, which speak a mechanical language all their own". This lyric can be taken literally, or it can be read metaphorically as a description of MIT student culture. Allan Sherman's paean to initialisms, "Harvey and Sheila", notes that Harvey "works for IBM; he went to MIT, got his PhD".
