Later in 1998 the game Half-Life offered improved graphic and true 3D.
Doom featured pseudo-3D graphics and item drops in maze-like levels full of monsters. The FPS genre was popularized in 1993 with the famous Doom game for personal computers running the MS-DOS command line operating system. As these games feature firearms and movement, the parent category is action games. First-person shooters (FPS) are a subgenre of shooting games and feature a point of view where the players see through the eyes of the game character.
