The Hyperdimension Neptunia series is rife with video game gags and obscure references. Planet Destroyer Black Heart, a strategy RPG starring Lastation leader Noire, is no different. One of the playable characters looks like a parody of Solid Snake from the Metal Gear Solid series. Rid is described as a cool character with a serious personality. She surprises cowardly enemies with traps and her favorite one is hiding in a cardboard box. You can see this skill in the trailer and it’s called "Stealth Hunting" in the Vita game.
Ester is probably a Dragon Quest parody and a riff on Erdrick, the hero from the first game in the series. Her personality is for better or worse naive and she calls herself a hero. When she sees something evil she rushes into action, which often gets her into trouble. Ester is looking for some legendary item.
Hyper Goddess Creed Noire: Planet Destroyer Black Heart comes out for Vita on May 29, 2014.
