Black ops-crossbow options

I'm planning on using the crossbow a lot online in Black Ops when I get it (hopefully later today). It looks straight up badass. Can anyone tell me:

A. When can I unlock it?

B. What options do you have for stuff to put on it? Namely, can you get the sniper scope from the campaign?

I need something to keep me goin' until my copy arrives.:P

idk but the idea sounds really lame

I think you get it at level 33. Im not sure what the attatchements are. But I do know its a secondary weapon. If you dont wanna wait that long to play with it then you can get your fix in Sticks and Stones in the Wager Matches :P and I like your idea, play how you want to. Haters gonna hate.

I was wondering the same thing. Torque Bow from Gears of War is one of my favorite video game weapons of all time. I'm looking forward to getting the crossbow.

Great sig, by the way.
