Nekketsu Oyako

Nekketsu Oyako is a beat-'em-up by Technosoft released for the PlayStation in 1994 and the Sega Saturn in 1995. Neither version was released outside Japan. The title roughly translates to "Burning-Blood Family." The game is noted for its humorous presentation. For example, one stage takes place inside a whale, and alcoholic beverages (a healing item) can only be consumed by Rando while his two kids get an "adult only" message instead.

Middle-aged housewife Saeko Hibino has a secret: she's actually a Nobel laureate theoretical physicist who devised a completely new type of antimatter fusion reactor at only 17 years old. But when a band of no-good bad guys calling themselves the Haraguro-dan find out, they figure she's perfect to help them complete their ultimate secret doomsday weapon and kidnap her. Her family aren't going to take this lying down, though, and immediately take up arms, setting out to free her by whatever means necessary!
