Panther was produced by Irem in 1981. Panther is a game similar to shooters like Phoenix, Galaga etc. p.p. You stear a tank at the bottom of the screen with a 2-way-stick. (LeftRight) Similar to Missile Command you have to save city, that are right behind you. From the top of the screen enemy tanks run down into your direction and try to destroy these cities, by shooting'em. The interesting point is the way you can shoot. How far the shot is, is set by a thing like a throttle, which has the shoot button on the left side.
