Doom (1993 video game)
"Doom"s original release date was the third quarter of 1993, which the team did not meet. By December 1993, the team was working non-stop on the game, with several employees sleeping at the office; programmer Dave Taylor claimed that working on the game gave him such a rush that he would pass out from the intensity. Id began receiving calls from people interested in the game or angry that it had missed its planned release date, as hype for the game had been building online. At midnight on December 10, 1993, after working for 30 straight hours, the development team at id uploaded the first episode of the game to the internet, letting interested players distribute it for them. So many users were connected to the first network that they planned to upload the game to—the University of Wisconsin–Parkside FTP network—that even after the network administrator increased the number of connections while on the phone with Wilbur, id was unable to connect, forcing them to kick all other users off to allow id to upload the game. When the upload finished thirty minutes later, 10,000 people attempted to download the game at once, crashing the university's network.
Doom (2016 video game)
Months after "Doom" was released, Zen Studios developed a virtual pinball adaptation of the game as part of the "Bethesda Pinball" collection, which became available as part of "Zen Pinball 2", "Pinball FX 2" and "Pinball FX 3", as well as a separate free-to-play app for iOS and Android mobile devices. At E3 2017 Bethesda announced "Doom VFR", a virtual reality adaptation of "Doom", compatible with the PlayStation VR and HTC Vive headsets. In "Doom VFR" the player assumes the role of Mars' last survivor who, after being killed, gets his consciousness uploaded into an artificial network, and is tasked with defeating the demons and restoring the facility's operations, having an array of electronic devices and weapons at his disposal. The game was released on December 1, 2017.
