1970s vector graphics experiments 'Maze War' and 'Spasim' defined the first-person shooter genre
The first-person shooter genre originated in the 1970s with 'Maze War' and 'Spasim', which used vector graphics to create 3D perspectives before modern hardware existed. 'Maze War' debuted in 1973 on an Imlac PDS-1 minicomputer, while 'Spasim' followed in 1974 on the PLATO network. These games introduced real-time movement and combat mechanics that replaced traditional target shooting, establishing the foundation for later titles like 'Doom' and 'Call of Duty'.
