Hey, I just picked up BoB during XBL's avatar game sale this last week, and I have a question about the DLC that I need an answer to before I start the campaign.
In the cases of the two DLC which provide new classes, if you buy them, do those new classes appear in the original campaign, or only in their respective DLC campaigns? I might be a little slow, but I can't tell from the wording when I go to purchase them.
I'm not sure if I want to buy the DLC yet (quite possibly after I actually play the game some!

), but on the other hand, I don't want to start the campaign without buying it if I'd be missing out on features the DLC provides.
Could somebody please set me straight? Thanks, looking forward to getting into BoB.
