Bucky O'Hare © 1992 Konami Company, Limited.

Bucky O'Hare is a scrolling shoot-em-up for up to four players based on the TV cartoon series Bucky O'Hare and the Toad Wars. Players must stop the Toad Empire from invading their home planets in the 'Aniverse' and enslaving their people. To achieve their goal they must shoot their way through an army of brainwashed toads to destroy their evil leader, a computer program known as 'KOMPLEX' and release the 'Interplanetary Life Force.'

Players choose to play as either Blinky (a one-eyed android), Bucky (the heroic rabbit captain), Dead-Eye Duck (a four-armed mallard) or Jenny (an 'Aldebaran cat' and telepath). Differences between the characters are purely visual as each plays the same.

In addition to their gun, each character carries a small number of smart bombs that can kill multiple enemies. Weapon and health power-ups appear at certain points in a stage, appearing through a glowing 'door' outline, that opens and throws the power-up into the stage.

Some stages feature locked cells in which Bucky's people are imprisoned. These can be shot open to release the prisoners. The game is mainly viewed from a side-scrolling perspective but will sometimes switch the viewpoint from stage-to-stage, with some stages using a forced isometric perspective or a vertically-scrolling viewpoint.

A large boss character awaits players at the end of each stage. "Bucky O'Hare" features eight stages of play:
Stage 1: Planet Warren
Stage 2: Planet Punk
Stage 3: Climate Converter
Stage 4: Asteroidbelt
Stage 5: Planet Rat
Stage 6: Mother Ship
Stage 7: Toad Star
Stage 8: Planet Life Force
