Doom did not invent the first-person shooter, but it might as well have. id Software's 1993 masterpiece combined blistering speed, demonic imagery, a legendary metal-inspired soundtrack, and revolutionary networked multiplayer into a package that became a cultural phenomenon. The shareware distribution model spread the first episode across the planet like wildfire. Doom modding created one of gaming's first major community scenes, with WADs (custom levels and total conversions) still being made over thirty years later. It established the template that shooters would follow for the next decade.
