Couldn't resist and bought it on the weekend. Crossbows are just awesome, the sound they make is great
Though they seem quite overpowered with really quick reloading and I started a new char lacking the quick shot perk. Since crossbows use the archery perks it should become even faster, I guess.
Oww, and nice is that the sound is quite loud and making enemies around you aware. So sometimes you're thinking twice before taking the shot or make extra sure you gonna kill with it... I like that. Adds to my gameplay ;)
