What was the original first-person shooter? Two largely forgotten computer games from the 1970s ushered in the genre

Two largely forgotten 1970s computer games, Maze War (1973) and Spasim (1974), are generally considered the first first-person shooters. Developed on powerful minicomputers at NASA and the University of Illinois respectively, they pioneered 3D first-person perspective gameplay with networked multiplayer combat, paving the way for modern FPS games like Doom and Call of Duty.
