Activision has announced that its DS music game Guitar Hero: On Tour has sold more than 300,000 units in North America during its first week on sale.
The company claims this makes it the publisher's largest North American launch for a DS title by a factor of eight, and one of Activision's top 5 best-selling launches ever.
"Guitar Hero is one of the most successful entertainment properties and continues to push the boundaries of innovation with Guitar Hero: On Tour," said Mike Griffith, president and CEO, Activision Publishing.
"The game's breakthrough peripheral brings the Guitar Hero experience to the 41 million DS users in North America and Europe, where they can play anywhere, anytime."
Two Activision bosses were recently paid overUSD 6 million in bonuses as the company's merger with Vivendi - the parent company of Blizzard - is expected to be complete on or around July 9.
