When you pop in your Crackdown disc
next week to download the Halo 3 beta
(we kid ... the beta won't be live until at least March) you'll be momentarily stalled for a title update. Noticing some considerable lag during co-op matches, both online and off (system link), Realtime Worlds cracked open the gold copy
and got back to work. The update should address these issues.
Phew, last minute patchwork sure beats a recall...
