Treasure, the publisher of this Sega Dreamcast shooter, gave away five copies of this game as part of a high-score competition in Japan. The game is the exact same as the original except it comes with a special sticker, two Bangai-O calling cards signed by a designer (HISASHI FUJITA), and a Bangai-O poster.
Auction Here – In 2011 one sold for around $800.00.
