The Joker menaces to blow up Gotham city's power plant and plunge the city into darkness once again! Help Batman defuse all of the Joker's bombs in every level of the power plant to save Gotham City. If a bomb's timer reaches zero, the bomb will explode and Batman will lose a life. Every bomb has it's own timer. Some bombs explode faster than others. Plan ahead and defuse those first! Accumulate as many extra seconds off the bombs' timers to score big bonus points. Watch out for toxic chimneys, conveyor belts and cranes.
