put the mission in advanced mode set it to intro, now whatever camera or stuff you put in here will be only the intro and when you set and ending trigger that will make the intro end and go into the mission. Now i suggest you read rob's simple camera tutorial, remember the name rob, then look up snypirs next after that. You'll need the command reference website for animation lists and all that editing goodness too. Just ask me if you don't have any links to this stuff im talking about.
