It's known as medabots in the U.S. There's two versions of the game. But only one translation is needed. It's obvious that these games won't be released in the U.S. because medabots has been dead here for years. The anime went off tv in early 2004. And the last video game was medabots infinity for gamecube which came out in dec. 2003. Here are some links for the game:
