It seems that Crackdown
still isn't allowing users to access the Halo 3
beta. We checked our own copy and sure enough, the beta option is still unavailable. Bungie is aware of the issue and Frankie has commented on it, saying it should be a short delay (hopefully). Those entering by other means shouldn't have any problems. We'll let you know as soon as we hear anything different.
