Activision and Valve announced an agreement to get Valve’s Steamworks on the PC version of upcoming Call of Duty: Modern Warfare 2.

According to the release, “All PC versions of Call of Duty: Modern Warfare 2 will be powered by Steamworks, providing gamers with auto-updating, anti-cheat technology, Steam Achievements, and the recently introduced Steam Cloud.”

MW2 will come loaded with 50 Steam achievements and will be accessible from any computer with Steam Cloud.

“Steam is the hands down leader in offering a community focused experience on PC and the inclusion of Steamworks has allowed us to deliver the most feature-rich PC version to ever come from Infinity Ward, which at the end of the day will mean the most to our fans,” said Infinity Ward’s Robert Bowling.

“Call of Duty: Modern Warfare 2 may be one of the biggest releases in video game history,” said Gabe Newell, president and co-founder of Valve. “Having a game as significant as Call of Duty: Modern Warfare 2 using the suite of back-end services in Steamworks is a signal to us that we’re making the right kinds of choices for triple-A developers like Infinity Ward.”

Also, starting today, Call of Duty: Modern Warfare 2 will be available for pre-order on Steam.

On a side note, the minimum PC requirements for Call of Duty: Modern Warfare 2 were also made public today hours before the Steamworks news.
