Turn off your computer sound. Right now. This clip's audio quality (and picture quality) is horrid. However, it does show off a special attack, the likes of which gaming has never seen.
Keiji Inafune is the creator of Dead Rising and former producer of Mega Man. Inafune has never been shy about voicing his opinion about the Japanese gaming industry, making him a living and breathing special attack.
In Hyperdimension Neptunia 2, he's an in-game attack, folded arms, glowing eyes and all. The game is once again, a send-up of the gaming industry.
Be sure to read Kotaku's review of the first Hyperdimension Neptunia.
