Halo 3 Epsilon

It seems another Halo 3 Beta test is underway but only in secret if you’re invited to be part of the exclusive member trying it out. Sound like the Freemasons. Xbox Live players have reported seeing other players indulging in a bit of Halo 3 Epsilon. An anonymous email has also confirmed that Epsilon is a new build of the beta complete campaign mode to try out. Are you jealous yet, are you, are you?
