The phrase refers to the action of acquiring, usually through electronic means, a digital copy of a particular first-person shooter computer game released in 1992, set in a 3D environment, for play on a personal computer. An example would be seeking to obtain the software files necessary to run the original or a modified version of that game on a modern operating system.
Access to this game, either legally through its current owners or through archival sites preserving abandonware, provides a valuable link to the origins of the first-person shooter genre and early 3D gaming technology. It allows enthusiasts to experience a landmark title that significantly influenced subsequent game design and technological development. Its historical significance lies in its pioneering use of pseudo-3D graphics and fast-paced action, setting the stage for future immersive gaming experiences.
