Ha ha, but who plays Modern Warfare 3 on PC amirite? Well, people do in numbers enough that Activision's finally decided to sell them the "Content Collection 1" made available to Xbox 360 gamers earlier this year. It's the first post-release content to become available for this version of the game.
Content Collection 1 will be available on May 8, offering four multiplayer maps and two Spec Ops missions, stuff that Call of Duty Elite subscribers have been able to play since January, and others have been able to purchase since March (and April on the PS3.)
