Barrage is an artillery game for two players who take turns playing the game on the same computer. Each player controls a gun and has to shoot projectiles at the other. Both sides have 100 men, and the aim is to kill the all of the enemies' men. There are two cities on both sides of the screen, which have to be avoided from being hit as it would incur penalties otherwise. The landscape is generated for each new match, and they are terraformed by the craters caused by artillery hits. Each player has to enter values with the keyboard for the angle and velocity of the shot while accounting for the wind speed and direction. Players with more than 35 men in the army will be asked to choose a delta angle and velocity which decide if shots will be spread out or fired in a small cluster. The number of shots taken depends on how many men the player has left.
