Valkyrie no Densetsu

Valkyrie no Densetsu (ワルキューレの伝説, lit. Warukyūre no Densetsu) is a platform/shooter arcade game that was released by Namco in 1989, only in Japan; it runs on Namco System 2 hardware, and is the sequel to an old 1986 Famicom game known as Valkyrie no Bouken: Toki no Kagi Densetsu. It was also included in the fifth volume of the Namco Museum series for the Sony PlayStation, under its English-translated title of Legend of the Valkyrie, much like how Genpei Tōma Den, which had been released three years earlier, had been released as part of the fourth volume under the title The Genji and Heike Clans - and much like that game, it uses a Yamaha YM-2151 FM sound chip for its songs but it uses the C140 custom sound chip for its effects and speech (as opposed to a PSG and a DAC).

The players must take control of the eponymous Valkyrie (who, for those of you who have not played the original Valkyrie no Bouken, is not an actual Valkyrie from Norse mythology but a warrior maiden from the heavens, who happens to be named after them), with her newly-introduced sidekick Sandra (an anthropomorphic green lizard-woman, but the fact that she is female is not immediately obvious); the pair must make their way through eight multi-scrolling stages by firing shots from their sword and trident at the various enemies that approach them, and the bubbles and coins that they leave behind when killed can be collected and later exchanged for magical spells with Babasama (an elderly male sorcerer) and special weapons/extra energy with Zoul, a travelling salesman who has his own realm.

Sandra would later go on to get a game of her own, named Sandra no Daibōken: Valkyrie to no Deai for the Super Famicom in 1992, which was also released in the United States and Europe as Whirlo.
