More Info:
"Description: Treasure Co. Ltd. (株式会社トレジャー Kabushiki-Gaisha Torejā) is a Japanese video game developer, founded by former employees of Konami on June 19, 1992. Treasure is best known for classic-style action games that employ innovative gameplay systems. Their greatest commercial successes have been games like Wario World and Mischief Makers, but they are better known for their critical successes, such as Gunstar Heroes, Dynamite Headdy, Alien Soldier, Guardian Heroes, Radiant Silvergun, Bangai-O, Sin and Punishment: Hoshi no Keishōsha, and Ikaruga. Their debut game was Gunstar Heroes, although McDonald's Treasure Land Adventure was developed first.

Treasure is a small, privately held company, consisting of around 30-40 members, though this number is somewhat misleading as they also employ independent contractors to assist development and sometimes partner with other companies like Nintendo, G.rev, and Sega to increase the size of their teams.

Because Treasure is a small, independent company, they generally depend on outside partnerships to finance development. As a result, they have worked on many titles based on licenses, including Astro Boy, McDonald's, Bleach and Tiny Toon Adventures, as well as partnering with companies like Sega, Enix and Nintendo to produce original properties. They have produced a handful of games independently, most notably their arcade shooters, Ikaruga and Radiant Silvergun."
