Crossfire is a shooting board game manufactured by Milton Bradley. The object is to shoot marbles at two little rolling targets. Eventually, one target is supposed to go into your opponent's "end zone" and you win.
Let me elaborate.
The Crossfire board is an elongated regular hexagon. In the center of each end lies a red marble gun. Little metal marbles (or giant BBs) can be loaded into the top, and when you pull the trigger, they are spat out onto the game board, one by one. On either side of the gun is a gully used to collect marbles shot by the other player.
The remaining two pieces of your Crossfire game board are two larger marbles inside purple plastic contraptions. These are the targets which you must push (by shooting) into your opponent's marble catchers. It's a very simple game with a lot of appeal for little boys who like to shoot. Unfortunately, playing a successful game of Crossfire requires a friend, and when you don't have any, all you get is another lonely Christmas gift on the shelf.
Anyway...
There are a few caveats with this game. The first is that the board surface is made of cheap paperboard and does not stay level. Obviously, this disturbs game balance.
The guns jam often when fully loaded. This can be remedied by wiggling your finger around in the chamber or by smacking the gun a few times to loosen the marbles.
Stalemates are very easy if one player runs out of marbles. Since this isn't in anyone's best interest, they don't last too long.
