Activision still hasn"t confirmed the existence of Guitar Hero Van Halen, despite both internal leaks and a German ratings board listing appear to have let that cat out of the bag months ago. And if this latest rumor turns out to be true, then we have the most solid evidence yet -- Destructoid reports they"ve gotten hold of the Achievements that"ll appear in the Xbox 360 version of Guitar Hero Van Halen, which may offer the first details of what to expect from the game.

It"s worth noting first that Destructoid doesn"t give any indication of where this Achievement list comes from, only assuring that they "have every reason to believe" it"s legitimate. So read on, but consider this still very much a rumor for now.

According to this list of Achievements, we know at least five songs that would be included in the game -- one Achievement specifically names "Little Guitars," "Cathedral," "Spanish Fly," and "Eruption." And the names of three other Achievements at least suggest that "Runnin" with the Devil," "Ain"t Talking About Love," and "Jump" will be included as well.
