I wish they would send me my fucking beta key, they say they give priority to charlie oscar delta vets an cod4 beta testers, an i aint fucking got mine!
Played the beta, the train yard map is fucking well glitchy i hope they sort that out! lol other than that its a fun game i guess. Defo one for the pc though so i can have my mods an custom maps like the old cod days!
register on the COD website, you should get it from there, no sure how long it takes tho, I have been registered for a while so it just appeared in my inbox.
