Cosmic Battle

The prototype of the Cosmic Battle is the game Spacewar!, written in 1961 by programmers of the Massachusetts Polytechnic Institute for the PDP-1 computer. The gameplay of this game is quite primitive — two players, each controlling their own spaceship, exchange fire against the background of the starry sky, trying to avoid both the shots of the opponent and the star on the screen, which attracts ships and destroys them when they touch.
