Microsoft has remained quiet on rumours that another Halo 3 beta test is currently getting under way.
Word spread after keen-eyed Live gamers spotted others playing something called Halo 3 Epsilon, supposedly later confirmed as a new build of the title by an unhelpfully anonymous email.
According to the mysterious note, Epsilon will let you battle across six multiplayer maps, play custom games, enjoy a single co-operative campaign level, use the Forge feature and get to tinker with the full Saved Film functionality.
Unfortunately it looks as though this will be a closed affair for a select few, but with the game a little over a month away, we can quite happily wait.
Halo 3 recently became the fastest-selling pre-ordered game ever, soaring past the huge one million mark last Thursday.
