PC gamers still planning on picking up Call of Duty: Modern Warfare 2 may want to take a look at the Steam version, which is getting full Steamworks integration, including Steam achievements and Steam Cloud support.

The achievement stuff is just delicious candy, really, but the Steam Cloud support is nice. That server side storage of your multiplayer game progress is the kind of convenience that I adore—even if I never personally use it.

Gabe Newell, Valve bigwig, sure sounds pleased about the adoption of Steamworks by Infinity Ward. "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," he says, dollar signs in his eyes.
