I'm doing something like that at GameStop, they are going to have some chow from Chick-fil-a and free Monsters for the people that pre-ordered, and they are setting up a big CoD4 tournament. Also the U.S. Army is coming to give away some hats and shit and I guess try to get people to enlist lol. It all starts at like 9:00pm and goes till they are sold out of games.
I'm stoked about it all, I even ordered a custem T-shit to where to it. It has a MW2 wall paper on the front and my Clan logo and my GT on the back. It will be bad ass.
