Don't worry, you haven't woken up in 2011. Sledgehammer Games have announced that a Call of Duty: Modern Warfare 3 demo will be releasing today, Thursday 23rd August.
Here's what Sledgehammer have to say:
"Do you know someone who's been hiding under a rock for the last year, and still hasn?t played MW3? Then you?re in luck!
The free demo for Call of Duty: Modern Warfare 3 releases tomorrow, August 23rd on Xbox Live ? featuring one of our favorite single player missions ?Black Tuesday.? Why are we releasing it now, you might ask? Incredibly, there are still people out there that haven?t played a Call of Duty game.
Crazy, right? So help us spread the word by tweeting using #MW3demo, and you could possibly get a direct message from the @SHGames account with a free Collection 3: Chaos Pack code for Xbox Live. Don't worry, PS3 friends, we have you covered. Stay tuned for more details soon."
