Résumé

Rabio Lepus Special is a horizontal shoot' em up, adaptation of the 1987 arcade game Rabio Lepus , known as Rabbit Punch in North America.

This port makes numerous changes from the 1987 arcade release, many of which aim to rebalance the game for a home console release. The first eight stages have been condensed into two stages, resulting in as half as many stages as the arcade game, various enemies and bosses were rearranged, and a few bosses have different attack patterns.
