Call of Duty Series and GUN Coming to Steam

Activision and Valve have announced an agreement that will bring "Call of Duty," "Call of Duty: United Offensive," "Call of Duty 2," and "Gun" to Steam.

"Activision has been a player on every major gaming platform dating back to the Atari 2600," said Gabe Newell, co-founder and president of Valve. "We're delighted to welcome them to Steam, and offer this legendary company's products."

"Our agreement with Steam enhances our current online distribution model by allowing us to bring our games to the broadest possible audience," said Dave Anderson, Activision's Senior Director of Business Development. "As broadband penetration continues to grow worldwide, offering our titles digitally to the millions of gamers connected through Steam makes sense to us."
