If you're one of the five people that hasn't got Modern Warfare 3, you can play it for free this weekend via Steam.
Activision is hold a 'Free Weekend' on the PC digital service, allowing gamers to download and play the multiplayer mode - the bit most care about - completely free.
The free trial will give you access to the game's entire multiplayer offering until Monday, when it will shut you down and hold out its hand for cash to continue playing (thanks Joystiq).
Activision yesterday released the first footage of this month's (on Xbox at least) new DLC map, Overwatch. Check out the video here.
