Halo3.com notes that the first way of getting into the Halo 3 public beta-- the web registration form that offered any and all comers in the U.S. a chance to be chosen-- has closed. Winners will be notified sometime this week.

Those who don't make it can still get in by buying a specially marked box of Crackdown, or entering the Rule of Three promotion the first three days of February by playing 3 hours of Halo 2 multiplayer between Feb 1 and 3 and being one of the first 13,333 to register at Halo3.com afterwards.
