Released in 1993 by id Software, DOOM is one of the most influential video games ever created. Developed by a small team including John Carmack, John Romero, Adrian Carmack, and Tom Hall, DOOM built upon the success of Wolfenstein 3D and pushed first-person shooters into a new era. It introduced fast-paced gameplay, networked multiplayer (including deathmatch), and a powerful engine capable of rendering pseudo-3D environments with dynamic lighting and texture mapping. Distributed via shareware, DOOM spread rapidly across PCs worldwide and became a cultural phenomenon almost overnight.
DOOM’s impact went far beyond gameplay. It popularized modding, allowing players to create custom levels, textures, and total conversions using WAD (Where’s All the Data) files. This openness led to an explosion of user-generated content and established a foundation for community-driven game development. DOOM also played a key role in advancing PC hardware, pushing adoption of sound cards, faster CPUs, and eventually 3D acceleration. Its influence can be seen in countless games that followed, from Quake to modern FPS titles.
As technology evolved, DOOM was open-sourced in 1997, leading to the creation of numerous source ports—modernized versions of the original engine designed to run on new hardware while preserving the original experience. One of the most important of these is PRBoom, a highly accurate and performance-focused port that emphasizes compatibility with classic DOOM behavior. PRBoom and its enhanced version, PRBoom+, are widely used for speedrunning, demo recording, and archival purposes due to their faithful reproduction of the original game engine. Today, DOOM remains a cornerstone of gaming history, continuously ported to new platforms and celebrated for its design, community, and enduring legacy.
