If you order this title directly from Interplay, you get a "bonus mission CD". However, this CD does NOT work without obtaining another patch from Interplay due to a change in the mission file structures before the game went gold.
The Dynaverse feature does NOT work out of the box. Apparently Flipside.com, the planned host of the Dynaverse servers, backed out of the deal after the game went gold. Interplay is scrambling to create new servers in-house, but there's quite a few complaints.
