Spasim
Spasim (space simulation) was a 32-player 3D networked game involving 4 planetary systems with up to 8 players per planetary system, it was released in
March 1974 and is claimed to be the very first
first-person shooter and a reward of US$500 is put up to anyone who can document an example of a multi-player 3D virtual reality game prior to
Spasim. , In Spasim the players flew around in space and to each other they appeared as wire-frame space ships. Their positions was updated about every second.
The game was played on the PLATO network. Other games on the PLATO network included airace by Silas Warner that evolved into airfight (possibly by Kevin Gorey and popularised by Brand Fortner), and then spawned US Army's Panzer tank simulator which spawned Panther by John Edo Haefeli at NW University. Atari, Inc had a PLATO account and Panther is said to be the origin of Battlezone while airfight led up to Sublogic's Microsoft Flight Simulator.
