Halo 3: ODST disc into the drive, because it's time to play some Halo: Reach. Bungie has just informed us that the beta, which runs until May 19, is now live. Have you watched Aisha Tyler's informative introduction yet? You don't want to waste time fiddling with the controls on your first day.
Let us know how the download process goes and what you think of the game once you're set -- assuming it all goes smoothly. You're not preparing another outrageous letter, are you?
Some quick words of warning from Bungie: "The download process may be subject to extended wait times. Server load is expected to be extremely high, especially during the first few hours and days of Beta availability. Please bear with us and stay tuned to Bungie.net for news and information."
