Crossfire is a board game released in 1971 by Milton Bradley. The game is very simple, two players would try to score goals by pushing one of the two pucks into the opposing players goal. This was accomplished by shooting small metal bearings at the pucks using the guns attached to either end of the board. The very first version of the game had a flat board, later versions were dome-shaped.
Each player started the game with twenty metal bearings, reloading could be accomplished by using any balls that had landed in the goal area. Because of the rapid fire nature of the game both players had to play offensively and defensively at the same time.
Unfortunately the Crossfire game is no longer in production, however you can find a few floating around on the internet from $100 dollars and upwards. A bargain for some quality nostalgia time!
