Activision has revealed all the details and information concerning the upcoming Call of Duty 4 Xbox 360 beta test. The biggest news being, for once it’s not merely US only but UK will be able to take part in the beta as well.
Starting on the 27th August, all you need to do is register at www.charlieoscardelta.com and you’re in with a shot of being selected to test out some of the single and multiplayer modes before the games released towards the end of the year. After the success of the Halo 3 beta, no doubt Activision will be dreaming about the possibility of masses of gamers getting extra excited about COD4 just before Christmas.
Why didn't they open up the beta to Canadian players like myself? The rest of the world has to wait until "early september" just to play the beta. :/
