Doom (stylized as DOOM or DooM in other media) is a 1993 first-person shooter developed and published by id Software for MS-DOS. Players assume the role of a space marine, popularly known as "Doomguy", fighting his way through hordes of invading demons from Hell. The first episode, comprising nine levels, was distributed freely as shareware and played by an estimated 15–20 million people within two years; the full game, with two further episodes, was sold via mail order. An updated version with an additional episode, Ultimate Doom, was released in 1995 and sold at retail.
