Spacewar was one of the first computer games of that time in history. Spacewar is a 2-player game that consisted of two spaceships, (triangles) firing torpedos, (dots) at each other while avoiding the gravitational pull of the Sun, (circle). The controls were simple too, w,a,s,d are the controls for player-1, and i,j,k,l are the controls for player-2. A,d are used to move your spaceship, and w is used to fire the torpedos just as simple as that.
