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.
Official versions of Doom
Both games are backwards-compatible with the Xbox One and can be purchased from the Xbox Store. They are also downloaded if the disc for "Doom 3 BFG Edition" is inserted into the console in lieu of the pack-in versions of the games included with that title, though the disc is required to play. They were also offered as a preorder incentive for the 2016 reboot.
