Modern warfare 3 beta keys?

Hello good afternoon! So it’s that time of year again, no not Christmas, it’s the annual COD releasing a terrible game we all scramble to play. My name is L and I’m an addict!

with that out the way does anyone know how to get a beta code free or have a spare one? I’ve preordered through a well known Keys site to keep costs down but would like to play the beta so I can see if it’s worth me ….who am I kidding if the beta is shocking I’m still going to get it. My parents must be so proud.!
