Ball Jacks (ボールジャックス, Bōru Jakkusu) is a 1993 action video game developed and published by Namco for the Sega Mega Drive in Japan and Europe.
Gameplay
Ball Jacks is a futuristic action game that involves an ultra-competitive sporting event. Two robot crabs are controlled by men who play the game merely to become wealthy and famous. There is a conveyor belt behind them that spews metal balls at them. The goal is to capture balls that belong to the opponent and keep them from him until time runs out.[5][6] Balls can also be knocked out from the mechanical hands of the opponent. All damaged crabs must return to the pit area for a quick maintenance and repair session.[5]
There are several modes: a world championship against increasingly tougher opponents, a multiplayer versus mode, a training mode, and a time trial where the time limit is the only foe.[5]
