1993 – 20 years ago, a Shareware copy was uploaded through a server at the University of Wisconsin (and although I was going to school there at the time, it wasn’t me – HONEST). The end result was the beginning of the first-person shooter. For those who do not want to read the Doom Bible, the story is about a Marine who assaults a senior officer, therefore was incarcerated on Mars at the Union Aerospace Corporation. His job was to overlook the teleportation device.However, the device goes haywire and a whole bunch of creatures come out of the portal. The player is told to secure until help arrives. Unfortunately, that means heading through the establishment and defending from the monsters that attack.
