This will definitely be one of the weapons I play around with. To be honest, I'm a crap Sniper Rifleman. There are those times when I can do pretty damn good with one of them, but at the end of the day it really is just luck, not skill. I'd imagine it'll be the same with myself and the crossbow in Black Ops, but hopefully I'll find some luck with this one.
It's also great to see that it does some good damage. One of my initial worries about there being a crossbow in the game was that it would be useless compared to the more modern (for the time) weapons. Based on the information in the original post, though, it seems like that isn't going to be an issue.
