This game was coin op made by sega and used kapu kapu's as targets. You used guns and it was a 2 seater game it is a 5 advancing on rail lane mechanical enemies towards the player with the player shooting them back a bit each hit if one of the lanes reaches the player they loose. The kapu kapu targets used in the game are most likely going to be blue and yellow in color. The question is what is the name of this game?
